Wonder what kind of dump or panic will happen when poloniex will release their 60000 bcc... (down to hell?)
And why do you think everyone will sell their BCC?, in fact I believe at most only 10k will be sold, rest will keep it as an hedge ,
Both poloniex and coinbase have stated they have not decided if they will allow buying or trading of BCH
So far all we know is they will allow you to withdraw to a wallet I dont know how this will affect things since a lot of people just keep their coins in coinbase instead of a paper/hardware or other wallet
GDAX said they will open BCH markets. And, Coinbase owns GDAX. So I assume you could also buy/sell BCH on coinbase as welleventually.
