I think that in the future this world economy will need bitcoin to be one of the solutions that can be relied on for the future, because I feel that payment using paper currency is no longer safe and comfortable, I'm sure the future will be more likely to use digital currency like bitcoin.
I strongly agree with your opinion, bitcoin will be the solution for future payments. However, I consider bitcoin as a combination with paper money. For certain groups that have higher education levels, bitcoin is certainly easier, cheaper and safer. But for people with low education levels of course using bitcoin is difficult and complicated.
