I mean, a place, where BCH, BSV, BTG, BCD et. al. can be exchanged with BTC?
time is proving that these hard forks are without purpose and are only to destroy the bitcoin image, see the recent bitcoin cash war what were the final results, the hard fork is over, altcoins that have arisen because of this conflict no have a great use, those involved in the war are accumulating many losses and the price of bitcoin fell from $ 6000 to $4000 probably due to this war. the result was disastrous
answering your question: as far as I know it does not have an exchange for this purpose, but I hope no one thinks of creating an exchange for this purpose
