I have sold all my coins that I had on my balance to buy ETC to participate in recent Calypso's fork. Current price is 1,6$, what do you think - is it worth to hold it or better to exchange on some oldy like WAVES or any other like that?
In my opinion the team managed the airdrop extremely unprofessional. They tried to reach out the Bittrex the first time two days before the drop and Trex rejected it.

Why? They make snapshot. Now mainnet is not starting. About what they need to contact with Bittrex? And all that we hear are from Bittrex team only.
Callipso technically is not exist now. On Yobit it is any token that yobit team give own members
