There are some people you will never be able to convince, no matter how strong your evidence is or how much you explain it to them. So, no matter what some people think, we should not care about them. Think about yourself: at one point, you were not where you are today, and some people never believed in you, but you are here today. Bitcoin will never be able to convince everyone. It does not need to convince anyone. There will always be people who will take it negatively. Everything has two sides, a negative and a positive. So does Bitcoin.
I never relied on others' opinions about how good or bad could be the Bitcoin. I have used it and experienced the movement, and after using Bitcoin for a couple of years, I strongly feel it has potential. If my wallets get hacked, it's my fault. I cannot blame Bitcoin for that.
