Can someone please share me the best exchange to claim free Ethereum forks? I am used to binance only but rumour has it that when it comes to fork binance takes too much time, sometimes up to a week or two, any other exchange that supports this fork?
Binance does support a possible fork, but does not promise listing of a new coin on the exchange. The fork and listing of ETH PoW is currently supported by exchanges such as Poloniex, Huobi, Gate, Bitmex, OKX and Mexc. This list is not final and it is possible that other exchanges will be added to it before the merger.
I think you are mistaken here, binance has announced that they will support for post merge ethereum fork. Supporting and listing a new coin does not affect them as they are just an intermediary providing services.
