BTC is with out a doubt ground-breaking and has gone unbelievably far. However that does not mean it will last the course. It does have issues and those issues are being talked about again and again with nothing happening. This will allow other coins that do not have the inherent problems that Bitcoin has to come to the fore.
People can make their choice as to which ones they think will succeed. If you see one, get in early, get it cheap. I have made my choices - make yours!
Bitcoin has already succeeded, and there are 0 alternatives that could offer the same levels of encryption and protection than Bitcoin delivers, not without the same tradeoffs, so stop dreaming for a "Bitcoin 2.0" moment because it's not happening.
If those Chinese farmers ever get tired of Bitcoin, the difficult would drop, so others would benefit. "Insane difficulty" is never a problem, is part of how Bitcoin works.
