For now and 5-10 years from now i believe bitcoin can replace as a number one currency like dollar and euro, because some people aleady know about bitcoin and the price keep higher.
Yes that's why I am using Bitcoin you are right for next 5 - 10 years Bitcoin is gonna take over many currency that's why some of the big investors have invested in Bitcoin and I believe that Bitcoin's value will be doubled in 12 months
How will it replace if the market cap is tiny compared to dollars? I think the bitcoin price will go up, but to go up 10.000 times? Do you see governments adapting bitcoin as national currency soon?
