A better Bitcoin in the form of a new generation of coins and blockchain that fits the current system is what we need. At this point, it is hard to achieve a currency or money that is not controlled by the state, the government always want to have control over everything, and it is the big reason why there are too many regulations regarding cryptocurrencies. This won't last, the newer generation will accept the fact that cryptocurrencies are here to stay and this is the future of finance. The efficiency it provides is way better and more secure that the fiat system.
