Let's face it a lot of people are going to be staying up and then sell all the alt coins as soon as they can.
I have been paying a lot of attention to the forum and it seems like if everybody is crazy and afraid of losing their money or their free coins, and this fork is very risky for the sellers and for the buyers, there is no middle term with this one.
Of course that i would hold my coins on my default wallet, and i will keep them in there until i am able to sell them for free money, if there is no replay action,then i would not sell them, and it is simple as that.
