Everyone will not like what we do for a living anyway, but what matters most it what we are doing for a living is putting food on our table than people speeches are worthless, it is still on the infancy stage and I understand that many people will look at it useless since it is still a baby. just like the story of the internet few years ago. It will be the same story that cryptocurrency is currently undergoing. Time will come and it will be mainstream. Don't bother the negative people around, just focus on your efforts and results.

One thing for sure. Bitcoin will stay in our world forever. Regarding on the security,Sometimes theres a lot of hacker out there but to make it safe dont try to open ur account in someones electronic device to secure your money.

 I think it is not because they fear bitcoin but it is what they think the better for the country because as we know, bitcoin has been used in many illegal activities including scams and etc.

I don't think so, because many people still using bitcoin as cryptocurrency. bitcoin turns into an investment place because it has no rules and standard price.

China wants to make its own virtual money
It is not impossible that China wants to create its own cryptocurrency that can be government legality.  But Bitcoin is also part of their economy there's so many Chinese that doing bitcoin and some of them are investors.

Bitcoin is really great but its volatile nature is really not future-proof. Every investment has its risk.
