The economy world is full of people who think bitcoin as a "bubble." They spread fear and doubt about bitcoin. They believe that the high price increase of bitcoin will encounter bubbles. but I think their critics and opinions are mere skepticism. It seems they just hate cryptocurrency. many of these people do not fully understand bitcoin. and they assume too far.
I face this with a doubt, I observe the year 2017 Bitcoin reached the highest price and this is a miracle. Everyone starts to find out about bitcoin. I feel the Bitcoin Increase is too fast so many people say "bubble". If it rises so fast then the price will fall quickly too, it's probably logic that makes sense.
so far I keep trying to convince myself that bitcoin currency is the future.
