Due to the fact of the update to CW2 it would be not a bad choice to sell now. Beyond this I recommend to watch how first Miners gonna react, even if they all accept it I think the price will fall down anyway, use this fall for your Sell orders and Rebuy when it is at correction. If CW2 get's accepted (what I do think is gonna happen) I think the BTC price will increase rapidly so be sure to check that movement out.
