you explained at length lol, but one thing is certain there will be no altcoin that can replace bitcoin, the reason is simple:

• Bitcoin's limited circulation, which will always be 21 million, is this limited supply which is one of the strengths of Bitcoin's appeal.
• Bitcoin has the strongest community, which is unshakable by anything and will not move to other altcoins
• Even though Bitcoin is closely monitored in various countries, the government is definitely studying it
• Bitcoin prices are very volatile, this is a big attraction

Maybe someone can add more
