The Ethereum Classic development team recently announced the Callisto Network Project which will result in a 1:1 CLO airdrop for ETC holders. Basically, you can receive free coins simply for owning Ethereum Classic come early March.
While some are mistakenly terming it an ETC hard fork, Callisto is actually going to be a new blockchain (with CLO as its native currency), developed in order to test experimental protocols, possible scaling solutions and set up a governance system which incentivizes both miners and coin holders.
If you want to buy Ethereum Classic, one of the most popular exchanges is Binance:

Callisto introduces a Cold staking protocol that rewards coin holders for being network participants.
Cold staking is defined as a way to incentivize CLO coin holders by allowing them to stake their coins and earn interest, without having to validate transactions, since consensus will continue to be achieved via Proof-of-Work (POW).
