Here I have outsourced the article explaining how to participate in Ice Rock Mining ICO:
1- First, sign up at Ice Rock Mining.
2- Now you fill in your ETH address under "my wallet" in your dashboard. It’s very important to use an ERC-20 compatible wallet, like MyEtherWallet, having access to your private keys. This is very important, otherwise you will not get your ROCK2 tokens later, because ROCK2 will be sent to this address after your deposit. Please use here NOT any address of an Exchange.
3- Next, you can purchase ROCK2 tokens by going to "dashboard" and choosing any payment method, like Bitcoin. Then you enter the desired amount, such as 0.1 BTC, activate the check boxes and then click on "buy xxx ROCK2"
Now you is shown the amount, you have to pay to the address, which you can see.
Here you can even send from Exchanges, because this part is only for payment. Your ROCK2 tokens will be sent to your ETH address from step 2.
4- Once you have sent the amount, you can enter your ETH address at etherscan.io , which you’ve used in step to, to recieve your ROCK2 tokens.
The transactions can currently take about 48 hours, since the demand for it is very high, but you’ll get the tokens.
When the transaction has arrived, then you have ROCK2 tokens in your wallet and you have to do nothing else, the mining revenues will automatically be paid into your wallet in ETH starting in July. If you have direct questions to the team, you kann ask:
