Which version of Bitcoin?

A little experiment I will be doing on Twitter. Whenever I see people shilling Bitcoin I intend to ask "Which version of Bitcoin?" in an attempt to pierce the echo-chamber. Maybe add a hashtag #WhichBitcoin

"BCH is Bitcoin" can sound scammy, but, "Bitcoin is the invention, not a particular blockchain" has better piercing power IMO and maybe will make someone think "There are multiple versions? Why? How?"

It's all instances of Bitcoin, the invention. Even Bitcoin Gold is Bitcoin. However - only 2 Bitcoin blockchains are really relevant, though. The idea is to challenge the "there can be only 1 chain" narrative. The 2nd thread of the Bitcoin experiment is growing and evolving and it's called Bitcoin Cash! The version that works as p2p cash magic Internet money!
