I have already transferred my BTC to an offline wallet (my Trezor) . . .
I'm now thinking to sell my Altcoins and doing the same to protect my BTC and collect free BCC.
What is everyone else doing with their Altcoins prior to 1st August?
no don't do this, hold them in altcoin on the exchange and not in bitcoin, because all the exchange are not safe on 1 august if you hold btc on them, because you don't know what chain they will be, some altcoin have raised now so it's a pity to sell them now just because of the panic of 1 august
