I have the same opinion that nothing can stop cryptocurrencies but we cannot underestimate governments, they are very resourceful, they have all the money in the world because they can print it and they can develop new technologies that could try to break the cryptography of bitcoin, as far as we know that is impossible but if you give to them enough time they could do it and we need to be ready for that.

But besides that the future of cryptocurrencies and specifically about bitcoin seems to be full of opportunities now the only thing that we need to wait for is if people really want the freedom that bitcoin offers or they prefer to keep being slaves to fiat.
