does anybody know a exchange that supports airdrop etc 1: 1 callisto coin? and what is the estimated price 
ETC FAQ:
What if I have my ETC balance on an exchange?
Each exchange has an account (or multiple accounts) where it stores its ETC. Technically this account will receive CLO at the time of airdrop in the same way as any other account. It depends on the exchange, whether it decides to give you CLO or dispose of them in a different way. We will contact the exchanges and publish a list of exchanges that will decide to distribute the CLO to their users here: https://github.com/EthereumCommonwealth/Roadmap/issues/422.8k
