I don't know if I would say "bitcoin is here to stay" as much as I would say "crypto is here to stay." I think just because bitcoin was the first, doesn't make it the best. The transaction fees and times are going up with network congestion. I would say that there is a bubble around crypto in general... especially bitcoin.. people are buying bitcoin because it is a buzz word, and they are entering the market without proper research. I think cryptocurrencies are eventually going to expose fiat cash for what it is and that the market will correct itself accordingly.
