Bitcoin is still not accepted in some countries.
Will it adopt by every country by this year end?
I don't think so, by the way, bitcoin still has scalability isue. It prevent bitcoin from mass adoption. Did you notice that when bitcoin price reach $20.000 then the fee is very expencive. I think bitcoin will be better if it stable on $11.000 - $15.000. But ofcourse it will be even better if the price keep growing but the transaction fee keep low.
