Many people believe that cryptocurrency is the currency of the future, but governments' adamant opposition means that, in my opinion, even in a decade, crypto will be the same. Alternatively, some countries may decide to develop their own digital money, like China did, in order to better manage its citizens, unlike bitcoin and other cryptocurrencies, which are difficult to trace. That might be their final option.
I think it is very unlikely that cryptocurrency will replace currency in the future. Although it is actually possible to happen to make it happen, it takes a long time. There are many challenges for a country that replaces cryptocurrency as the currency of the future.
Not unlikely but rather it would be impossible to happen because government would let it to happen on the first place and even if El Salvador had already done such pace but doesnt mean that every
country would definitely do the same thats why this would really be a never ending kind of debate on which lets just deal on what we are currently dealing with.
Its not really that needed to ignore but we shouldnt really be that optimistic on things that is nearly impossible to happen.
