I believe that until bitcoin has a stable value, it will not be used to the full. Absolutely rightly written in this topic above, until its price is unstable, it will be used only as an investment.
I do not think so. In my opinion Bitcoin can completely become a payment instrument. There are now many companies that accept Bitcoin in payment. Bitcoin is the technology of the future, maybe now people do not fully trust Bitcoin. In the future, I believe people will change their minds
