Cryptum ICO Stage II Sale – Project Update

Cryptum ICO Stage II starts on October 17:

Cryptum ICO Stage II sale is your last chance to take part in our multi-project ICO (check our this article and our Whitepaper for more information) with the following features:

  • Cryptum Board Games: the Cryptum ICO main goal is funding a board games publishing studio. We will share up to 40% of the profits with token owners by creating a pool that can be claimed based on the number of tokens owned (a percentage from each round). The shared profits are an optional feature accessible via claims. We already started developing three of the games – you can check our Blog and the Info pages in the top menu for more information.
  • Cryptumcoin ICO: Cryptumcoin is an Equihash-based mineable cryptocurrency we are launching in December 2017. We will distribute up to over 2.5 million CRYC among the ICO participants depending on the total number of Cryptum Tokens sold.
  • Tiers for free games access – with proof-of-ownership tiered access accessible if you own 25, 35, 65 or 100+ CRTM. Every tier gives you the optional right to claim free access to one, more or even all the games we ever publish.

Cryptum Stage II Sale

You can participate in the Stage II of the Cryptum ICO by purchasing CRTM tokens using BTC, ETH, ETC, BCH, LTC, DASH or ZEC. Note that any amounts lower than the shown in table will not receive CRTM and will not be refunded!


Changes from Stage I

After raising about $136 000 during Stage I, we realized we won’t make it to Mining project level of sales even in Stage II. Somewhere during Stage I and we received a sound advice from ICO Rating regarding the project – to devote on the board games. At the end, we made the decision to focus on the two aspects of the ICO that are most important to us: the board games project and the Cryptumcoin currency we are launching in December.

That means any side projects such as icodbase and the mining project are being cancelled, allowing us to concentrate our efforts to the board games and the Cryptumcoin. It also leads to a very important change regarding the total amount of CRTM, as we no longer need to sell so many tokens to get the funding we want – the maximum supply of Cryptum Tokens changes from 1.102 million to a bit over 156 000, with 129 520 available for sale during Stage II of the Cryptum ICO. The Stage II will continue to November 17 or until the tokens are sold, whichever comes first.

Initially we announced the prices will be 25% over the Stage I Sale amounts, but with the latest Bitcoin rate changes, we decided on a new approach. Instead of the ETH price, we are now using the BTC price as a base (and it remains the same 0.00135 BTC/CRTM). All prices include CRTM and CRYC transfer fees. The minimum participation amount is 25 CRTM (which is the same as Tier 1, so you will be able to get a bonus free crypto-mining board game when it’s released, and a share of the games profits each time we release a game on the market).

What do you achieve with these changes?

For once, we will be working harder on the games and the CRYC currency development, and we will not split the main funding to make a partial investment in a mining farm. This lowers the basic needs of the project to much more manageable levels.

  • The Cryptum Board Games project does not scale so well over $800 000, forcing us to seek and publish games that we may not want to. While generally this is a good idea, at around 150 000 CRTM we would have lowered the games funding for building the farm, meaning we would have needed higher ICO total funding for the same board games funding.
  • It also means now we will have the same profits from the games to share among much less potential token owners, and we can distribute more meaningful amounts of Cryptumcoin among the token owners while still keeping the coin pre-mine low.
  • The Cryptumcoin is being developed as a miner- and trade-centric currency together with Crypto Mining Blog. We want use it in our future games store and as advertisement payment currency in websites we are developing.


More Cryptumcoins per CRTM token

(Note that all information dependent on the amount of CRTM sold during Stage I is non-final. We will keep the ratios and final amounts as close as possible to the information below, but some calculations use the CRTM sold during Stage I and we are compiling it before its end).

In order to promote the change, we will be distributing much higher amounts of Cryptumcoins during their launch in December. Launching a currency that has both a fair launch targeted at miners and a large pre-mine, which are somehow mutually exclusive, is not easy, but we found a way to balance between the ICO supply and the coin effective supply (the supply in the most active mining and trade periods we call “ages”, see the table below) and the max supply. We are keeping the total pre-mine to between 0.42% and 2.64% of the max supply of Cryptumcoins (depending on final ICO sales) and between 2.22% and 12.70% of the ages of peak interest supply.

The pre-mine volume is based on the CRTM tokens sold during the ICO stage plus any bonuses, and varies between 397 823 and 2.6 million CRYC. It is distributed on the following conditions (formulas are explained in the notes, further information can be found in our Whitepaper):

CRTMsold1 CRYC per CRTM2 TOPx Bonus3 Additional Marketing4

100.5k-156.1k 12.93-14.95 CRYC/CRTM 77.9k-140.1k =(200k-Bonus)

1 Example categories starting from the current distribution of 19 776 CRTM and up to theoretical maximum of 156 118 CRTM incl. bonuses

2 Current CRYC/CRTM Rate (CRYCrate) = 10+(CRTMsold – CRTMstage1) / 27500). After the coin launch, token owners will have 30 to 45 days to claim their Cryptumcoins on our website. Please follow our social accounts on top of the page to avoid missing the deadline. Distribution will be done in waves on a first come, first served basis.

3 After launching the Cryptumcoin, and after the claims period is over, we will distribute an additional bonus amount of CRYC (Bonustotal = CRTMsold * CRYCrate * 0.06) to the top contributors based on the following formula: Bonustop = BonusTotal / TOPx where the number of TOP contributors is TOPx = (CRTMsold – CRTMstage1) / 250 if < of the total number of contributors, or else the number of contributors.

4 As we would try to list the Cryptumcoin on as many quality exchanges as possible instead of relying on voted listing, and considering the prices for listing a coin lately (3-5 BTC on some exchanges), we’ll need an extended marketing support. The formula here is: Marketing Budget = 200 000 – CRYCbonus.

In any case that doesn’t allow us to use anything but integers, we will be rounding in a way that leaves the difference in our wallet. Unclaimed amounts of Cryptumcoin will be considered forfeit.


Consider the following example:

If we sell a total 35 000 CRTM with 5% bonus on the amount sold during Stage II, we will distribute 35 760.88 CRTM to token owners, and, after the Cryptumcoin launch, any owner would be able to claim 10.58 CRYC per token (for a total of 578 387.35 CRYC, representing less than 0.6% of the theoretical future maximum supply of Cryptumcoins). Additionally, in this example, after the claims, we will distribute 22 703 bonus CRYC via aidrops to TOP63 contributors (355 each), we will have 11 351 CRYC for bounties (note that social bounties will only be distributed if we sell more than 55 000 CRTM total) and 177296 CRYC budget for exchanges listing.

Not in the table – we will have a bounty campaigns, distributing an amount equal to 50% of the post-sale bonus, but these will be announced after the Cryptumcoin pre-announcement.


Cryptumcoin features and goals

Creating a currency that can be equally attractive to miners and ICO investors is hard. There are number of other goals we had in mind, as well as solutions for them:

  • To create a highly popular currency. Being based on popular tech would hardly make it one of the TOP10 (although it has better chances than some of the top coins in WhatToMine), but considering how many poorly developed and meaningless cryptocurrencies make it to the TOP100 coins, we consider it paramount goal.
  • Protecting the ICO investments – basically making it popular is enough, but we also implemented low initial start and we will invest in early exchange listing so the ICO participants would be able to trade it early, almost everywhere.
  • Listed at the top exchanges – which requires mostly high volume. And the pre-mine will help with creating trade volume on smaller exchanges as a gateway to high volume trade on the big ones.
  • Friendly to the miners – with an early access to exchanges, pools and tools, and power efficient and well known algorithm, and meaningful block rewards that ae meant to expand it fast, there is no doubt Cryptumcoin is going to be widesperad and friendly to miners that hate to see 0.x in their daily earnings or 0.000000x cost at the exchanges.

Cryptumcoin is developed together with one of the leading mining blogs – Crypto Mining Blog, meaning it is primarily a miners’, trade-centric currency, but we developed in a way that promotes long-term investment value and that fights some common failures of other currencies launched in the past. We want to be able to use it as a main currency for our products and services in the future, and we don’t see any value in poorly copy-pasted currencies that cannot be regarded as even a short term trade opportunity, much less as a long-term investment.


  • Power efficient algorithm – we are using one of the most power efficient and ASIC-proof algorithms today. Equihash is still by far more favorable to your bills than almost every other popular algorithm. There are some examples of even more power-efficient algorithms, like ethash, but they are either farm-friendly, non-user-friendly or simply unpopular.
  • Less farm-friendly – with Equihash being clearly favorable to NVIDIA GPUs and NVIDIA being a bit late to the mining party, there are much less farms using “green” GPUs, and there are many more small miners using them, meaning you can expect more mileage out of your GPU. Plus the NVIDIA videocards are easier to find on the market right now.
  • Extremely popular algorithm – this is a bit of a double-edged sword, but it allows exchanges and pools an easy integration, there are far less problems expected on software level, and there is a better chance to make the currency known to more people. Last, but not least, everyone knows how to mine it. Of course, we will still explain it in details on our website!
  • Listed early at exchanges – we want to make Cryptumcoin popular. It will not happen only by holding Cryptumcoins in wallets, there has to be trade volume to allow it to enter the top traded currencies. With a fractional pre-mine (distributed as a small part of our Cryptum ICO) available to make it ready for exchanges since day one, and block rewards that quickly expand its presence, we hope to have it on every major exchange in less than 2 months.
  • Developed together with Crypto Mining Blog and advertised by such a leading mining media means the coin will receive plenty of attentionHigher initial volumes also allow us to promote trade and add it to CoinMarketCap and WhatToMine faster.
  • Announced early – with Pre-Announcement being part of the Cryptum ICO and starting well before the actual launch, we want to give equal chances to the ICO contributors to get involved and establish the trade market, and send a clear message to the miners what and when to expect.
  • All the tools available – it’s not a rare case to see a “day 1 fair launch” that only offers a Linux wallet and a CPU miner – this is usually done to allow the devs to mine early with impunity. We will provide all the tools and their sources together with the launch. Being an Equihash-based currency also helps as the miners are already quite popular.
  • Pools contacted ahead of the official launch date – we will contact some popular pools ahead of the launch so they can prepare for a zero day mining. Together with early listing at the exchanges, we want to create a finished ecosystem for the coin and give everyone immediate access to it.
  • Innovative block reward scheme that addresses almost most weaknesses of coin launches launches and targets some specific problems with distribution, inflation and availability.


Vision and Specifications

The theoretical maximum supply of Cryptumcoins is over 98.5 million coins, which is not unusually high. Still, we had to consider that it has some influence over the market price, and that we have a pre-mine for highly-mineable cryptocurrency. We have developed changes in the block rewards according to the block height, which we call Ages. These ages address the most common issues of newly launched digital currencies and are aimed at creating a lasting currency with slowly inflating price that can be considered stable.

At the same time, the ages also help us establish the Cryptumcoin as a coin dedicated to miners, and protect the initial investors that participate in the Cryptum ICO. For example, we will start with low block reward for the initial 8064 blocks. As this is the time when most ICO contributors are claiming their rewards (practically proving they own certain amount of CRTM tokens and confirming their address with a minimal ETH transfer from it), and we are listing the Cryptumcoin on as many exchanges it is possible, it is the ICO participants job to establish the trade with the early investors. Yet we will not start with completely useless rewards, and early miners will be able to take some advantage of the low difficulty.

The scheme is shown in on the image above and explained in detail below:

  • The Initial Age has a much smaller block reward that doesn’t promote early over-mining. Together with the fair launch and pre-announcement it will create equal possibilities to all miners. It also protects the ICO contributors investment early in the currency life while still allowing newcomers to mine and sell their coins to early investors.
    • The Slow Adoption Age is the time when most people learn about new coins; the block reward becomes 50% higher (but just a bit over mean value) while the difficulty increases with new miners joining in, meaning more people will get Cryptumcoins. It also raises the max supply to 3.25-20+ times the ICO premine (depending on the ICO sales).
  • The Rapid Expansion Age raises the block reward further with another 50%, right at the time of peak popularity growth, allowing great expansion of the coin presence and trade opportunities. This welcomes latecomers and doesn’t punish the people that started early, even after the difficulty increases by a lot. At the end of this age there will be over 15.4 million CRYC on the market.
    • The Expansion Adjustment Age lowers the block reward slightly (11.1%) to help fight deflation and even promote slight increase of the price. We expect that this will be a time of high difficulty mining, so we kept the reward about 35% higher than the mean value. At the end of this stage the Cryptumcoin will be hard to mine, yet there will be over 21 million coins on the market, allowing great spread and trade volume.
  • The Stable Age is basically an age of peak popularity and difficulty. At its start, the ICO premine will contribute to only between 2 to 11% of the total coins on the market (depending on the ICO sales), and this is when we plan to start using the Cryptumcoin for our services. The block reward is lowered with 12.5% over the Expansion Adjustment Age for the next 64512 blocks to stimulate trade and price growth.
    • The Price Adjustment and the Final Price Adjustment Ages lower the block reward further to promote a stable price inflation over time without delving into the typical halving of the reward that risks alienating the miners. With over 40% of the currency life ahead of it and stable, gradually inflating price, the Cryptumcoin will have a chance to become one of the top end cryptocurrencies and keep its place for a long time.

Detailed specifications, tables and additional information can be found in our Whitepaper. Additionally, you can visit cryptumcoin.com.

Together with the long list of features and specific ideas we introduced in the development of Cryptumcoin, we hope to establish it as one of the most popular crypto currencies on the market. You can participate early buying Cryptum Tokens – the Cryptumcoin is only a bonus feature of the tokens as they are helping us fund board games publishing, featuring shared profits and free access to our games, but each CRTM token owner will receive initial amounts of CRYC to use as he sees fit.

Cryptum ICO – games news, plan changes, Cryptumcoin

We just passed $110000 raised in ETH and BTC, and that cracks open a new possibility – to work on few games at once. We are in for another change of plan, and here it is.


Blockchain crypto mining game

As we are still unable to establish a contact with most of the big exchanges, we will proceed into the Blockchain crypto mining game development using only those that reply before the end of the Stage I sale, and agree to our conditions and supply us with high-res logo, slogan and permission to include them in the game. While the currencies information we use in the game is not a subject of copyrights, the exchanges logos, names and slogans are owned by the respective companies, and we cannot use them without permission, taking legal risks. But we are free to mock their lack of support and appreciation for our work, so you can expect some close representation of the “unofficial” versions. The game will enter active development the moment Stage I of the ICO is over, so if you have any way reaching the TOP10 exchanges, please remind them they still have few days to reply!

Because of the low Cryptum ICO sales, you can expect very high returns even from the Blockchain game – 20% of any profits after the Kickstarter campaign and future wholesale and retail deals. For example, if we raise $250 000 in KS (which requires only 4167 backers), and assume 30% off the KS price cost (remember, we will not include development in the formula, you’ve already paid for it), taxes and shipping fees,

The Cryptum Cryptocoin Project

We are preparing to launch our own mineable cryptocurrency with its own agenda. Every token owner would be able to claim the same amount of coins (based on their wallet content at the date we announce), and will be marketed as part of the Cryptum Network Projects as a high-value coin. We will develop all necessary user-friendly tools and use additional financing to make it as widely accepted as possible. We will also distribute claim-based aidrops based on low premine (up to half of the amount of Cryptum Tokens issued) to the top holders based on the amount held in their wallets. At a later stage the coin will be used to purchase products from the board game line range.
