I don't see Bitcoin as utopian money that is magically going to solve our issues. Bitcoin is marginally better than gold and significantly better than fiat. It IS the best money we have ever used as a species and therefore, I believe it will continue to grow in market cap. However, I won't be at all surprised if 300 years from now, the human race has discovered something better. If Bitcoin can bring us a marginally better world for the next 300 years where the purchasing power of billions cannot be arbitrarily diluted, the network will have fulfilled its noble purpose.
