yes I am using bitcoin since last 3-4 years and I can say its the future of currency.its using blockchain technology that is much better then centralized system.
I was practically a newcomer I joined the bitcoin recently.about 1 year. I began to recognize bitcoin
I think bitcoin still need development. but I am confident and believe bitcoin will last for a long time
Bitcoin will still need to develop more and more to sustain its rank among cryto currency and to resolve the problem about the size of the block.
I to believe that bitcoin will survive and will last for a long as i live.
