There are so many better crypto-currencies. Better for the environment because they use proof-of-stake, and not proof-of-work. Better for users because transactions are confirmed in seconds, not hours, and without the ridiculous fees that Bitcoin has. I think this shows how truly powerful the network effect, and being first to market is. Because without those things, Bitcoin would be nothing.
As a side-bar, a major role of money is to allow the government to easily collect taxes from their citizens and so governments have to be careful here as they must ensure that there are no challengers to their primary form of taxation payment. Bitcoin was very carefully crafted to survive government attack and finally the government accepted it by considering it a taxable commodity. While the early crypto-is-cash people are annoyed by this, it was the only possible outcome in a match between the government and crypto currency that doesn't end in outright warfare on crypto.
Now that digital currencies have moved from theoretical to a proven model people can move on to solving newer problems rather than just getting it off the ground. Now we have privacy coins which attempt to solve the problems of getting anonymous transactions among other desirable features. But wait there's more, now that we don't have to prove that electronic cash is a workable system we have decentralized finance coins now. If people thought the government hated bitcoin, just wait until the banking system realizes defi is coming.
