The reason most of us asking this question is because we have doubts about bitcoin and its future. If we just ride with the flow and where we going with the help of bitcoin, our financial life wouldnt be the same. If this is worrying us now, even with to much attention and popularity is higher today what more to those who invest in bitcoin 8 to 10 years ago. We being part of the community will be the one decide what future what we want to be, together.
The current condition should makes bitcoin users more calm since actually so far the progress is good. But don't hope too much, bitcoin will not replace fiat. It will be only alternative currency, since the price is very fluctuates it is not so appropriate for daily transaction.
No one out of us has ever thought of any such thing like that of virtual currencies in his mind but now there are so many crypto currencies. Same is the case when we talk about paper money and crypto currency. We never know what will happen in the coming days and that there are slightly chances that we may be able to see crypto currencies taking a lead over the real currencies.
