Ethereum Classic (ETC) is having an airdrop of Callisto (CLO - a cold staking sidechain crypto) at block 5500000, approximately March 5th of 2018. We are currently sitting around block 5432147. ETC must be held in the ClassicEtherWallet found on their website, or the mobile wallet by Coinomi will be giving out CLO as well. For anyone who thinks Ethereum Classic ETC is a sh!tcoin, it is the original Ethereum blockchain before ETH was hard forked after the DAO attack. ETC is now integreated with the IOHK's Daedlaus wallet. Charles Hoskinson who created Cardano and IOHK was one of the co-founders of Ethereum and now he supports ETC. I think a percentage of ETH's market cap could possibly shift over to ETC. Not saying ETC will take over ETH, but ETC could gain quite a bit in value.
