Bitcoin is fine historically. It is obsolete and it has failed to achieve its whitepaper goal of being an electronic cash system. Nostr and Bitcoin X are just a cult of greedy retards who parrot the same stupid shit like store of value, freedom, mathematically proven.
Everyone who isn't absorbed in the number go up bullshit understands why Monero or even Dogecoin is superior to Bitcoin.
In a way, the ostrich is a perfect maskot because it was meant to fly but chose to walk.
Nostr will not replace Twitter. As you can see bitcoin cultists are already leaving in droves. So who's gonna stay? Fedi folks who are interested in censorship resistance, Loli posters, a small number of folks from Iran and China.
Somebody already pointed out that Nostr is just scuttlebutt and will end up similarly.
