In my opinion, the majority of people in the world do not want fiat currency anymore, its value continues to decline as a cause and every year it experiences inflation. In some countries people have no other choice but to use local money, but in other countries they have alternative money namely Bitcoin and cryptocurrencies. Of course Bitcoin is becoming very popular today and the transaction value is increasing every year, people in the world prefer Bitcoin as an investment or transaction between countries because it is easier and can be converted into any currency. So we as a world community want a currency that really provides benefits, not one that harms its users.
Unfortunately, not all countries will easily permit transactions with bitcoin. it's easier and safer. but we can see how the development of bitcoin which is used as a transaction tool so far is still very little.
mostly, are investment assets that are held on the exchange or in personal wallets.
only in certain countries that the use of bitcoin as a transaction tool is allowed that we will be able to measure the level of satisfaction.
and when one or two countries succeed in implementing this, I think most other countries will consider switching to more secure and transparent transactions.
