It will take a lot of time for Bitcoin to prove itself. For now, although among our community, Bitcoin is the most trustworthy coin, people who doesnt know about cryptocurrency still think of it as scam or bubble. But I believe it will have a bright future
I do not know about Bitcoin proving itself. It already has to me. And remember, Bitcoin does not need to prove anything to itself, it is simply there available to be used and it is up to us if we want to take the opportunity offered by it.
It has proven itself to be even more than what people thought it would be over the years. It will continue to do so for many more years.
Although there are still some people who think that Bitcoin is not useful, but for people who have proven it then Bitcoin is a very extraordinary thing. Bitcoin is still in the process stage so we can not yet conclude that bitcoin can not be a global currency, Bitcoin is currently used by many people and the opportunity to be accepted is much better. I do not want to listen to people who are pessimistic, I am an optimist so I believe in the future of bitcoin.
