Bitcoin transactions that happened prior to the 2017 (August?) fork should still appear in BCH and BSV blockchains because BCH forked off of Bitcoin. Same should be the case with any other Bitcoin forks.
gotcha - I dont deal much with forked coins so did not think about the dates too much so while I thought it odd to see bch and bsv, I did not dig further than that.
the only forks I recognize by name are all 2017 and later.
are there forks from before the redeem date of the coin?
Yeah, caught me off guard too when I found that out the first time. I was like "I have never made any transaction on BCash, how come my address has so many transactions?" Then it occurred to me that it's just a fork of Bitcoin and not an entirely new blockchain.
Bitcoin forks before the redeem date, like 2015? I don't think there have been any prominent ones.
