Due to based on digital, many countries has adopted crypto currency, lot of work has been paper less.we should be thinking positive. So may be it will take time to grow up & give good earnings in future. I think so.
Yes, in general there are already several countries that have adopted crypto currencies, but if we look in detail there are still many countries that have not adopted crypto currencies because each country has different government rules.
Actually, to adapt as a means of payment from each country is not an easy thing and seems impossible because it will later change the structure of the existing order. of course the main hope is that support from all countries is not necessarily the hope that they can fully support it like Japan. now almost every country has begun to develop and new projects and ideas have emerged
