BitcoinHEX will not hold an ICO to raise money, they will instead airdrop BitcoinHEX to bitcoin holders that hold their private keys.
When you got your tokens after the snapshot you can stake them. The entire stake pool will get 3.69% wich will be distributed to the token holders.
After the snapshot you will have a period of 50 weeks to claim your coins but early claimants will get a bonus of 10% the first week, wich will decrease by 0.2% per week. After week 50 no one will claim.
