Btc and bch are legitimate forks of the same coin, created more or less with the same intent. Btc is a little more successful, but it’s very possible the crowd at Bitmain are playing a game to corner bch and drive the price suddenly up at the right moment. There was a recent article about ‘bch whales dispersing or selling’ large wallets into smaller wallets, which is what you would see before a scenario like that. There are other indications too that bch may launch a sneak attack through Asian markets. Starting with simple facts, btc and bch both have legitimacy, and the most clever crew will win.

Bsv was entirely created and has been marketed by a wealthy person who sees it as his empire. There is nothing legitimate about it.

All three of those coins are shitcoins, but bsv is by far the worst while bch and btc are better somewhat.

Another view is that ‘bitcoin’ versions are necessary for a while to coax the public into crypto. People form sort of gangs or teams around whichever ‘bitcoin’ their group thinks is best. Bsv has a legitimate market in that case, just like there are a lot of people who only want advice from a famous or rich celebrity.
