BSV will thrive. It is the closest to the original Satoshi vision. It was created to defend against contentious protocol changes that will prevent massive adoption.

This is part of "Blockstream's Vision" propaganda that is inconsistent. Prof Faustus claims the Bitcoin script is Turing complete which includes gambling - not that it matters anyway.
