BSV is the Bitcoin that hews closest to the original Bitcoin protocol design.
I see special people on Twitter quoting this all the time.
Just because it's in some marketting blurb for a shitcoin does not make it a fact. BSV is pure crystalized shit. BCH is distilled shit. End of story.
There is only BTC.
A 51% attack on either BSV or BCH is utterly trivial to the truly motivated.
I will moderate this argument as an unbiased 3rd party. There's no such thing as a "real" Bitcoin because longest chain rule does nothing to solve rough consensus attack, and Bitcoin has been hard forked before and will need to be hard forked again in the future to not implode, and even Segwit is technically a hard fork because it changed the security model, thus altering fungibility. A hard fork does not obey any 'longest chain' rule either, so there's no actual continuity making the whole system just a confidence game (garbage).
