Technically you may be right and having read the white paper multiple times I agree. But I don’t think bitcoin was supposed to solve all the worlds problems. It was a concept that beat the double spend issue. It was always going to need further development and evolution.
But bitcoin currently has first mover advantage and is the only real crypto with brand/ name recognition outside of crypto circles. It will take a lot to replace it in the short/ medium term.
I don't think BTC will be replaced in short term. Medium term, ETH would be a good pick. ETH has decent coverage and almost every place that sell BTC for fiat also sells ETH. localbitcoins is probably the only exception. There are other alt-coins rising and gaining recognition fast. In the long run BTC would be like the original iPhone which everybody remembers but used by pretty much no one at all.
I agree that beating the double spend issue was one of the biggest of not the biggest achievement of Bitcoin.
Yep
