In a few country, you can use bitcoin as currency not just transafer. Its true that many people still not able to use bitcoin in many country but i do believe that in near future, we will able to use bitcoin in many offline merchant and online merchant
Bitcoin is always fine and it is really safe to used. But the people who used it really doesn't have a big patience. From the start we can all see that the bitcoin price is high on volatility which can really have a constant change anytime. So we didn't really need to say that this bitcoin won't be fine, because I believe that it is already fine and nothing's change won the feild.
