forks are on a different chain, not the same, and don't trade the same. I doubt you'll find anyone who will do 1 BTC = 1 BCH = 1 BSV when you're trading it.
You have not prevented copying of the data. By your own admission, you have three forks of the same chain, all copies. The copying has already been completed. Case closed. All you're referring to now is claiming one confidence game scam is better than the other two, because that's the only selection criteria for which one someone picks, not longest chain, their simple opinion. A faith or confidence based monetary system is complete garbage. We already have fiat if you want confidence game scams.
