Maybe this question has been done..
Bittrex will support will give the x2 if you have bitcoin in your bittrex wallet??
thanks
Yes someone knows which exchange will support fork , there are few people who knows about it. I don't know about other exchanges and wallet but Coinbase is going to support the upcoming hardfork and it's also a good exchange so I'll hold all my Bitcoin in here to claim BitcoinSegwit2x after the hardfork .
