Agreed. Bitcoin is store of value. It will replace gold not fiat in future. Soon we will see digital version of all national currencies. China has already developed it didgiat yuan.
People will no longer use BTC for buying or selling, they will use as storage of value just like people do with gold.
I agree, not matter what country it will adapt it whether it is bitcoin or other crypto made by them still still the use, purposes, and the senses of fiat cannot be replace by bitcoin, fiat is very much in need in each country it cannot be replace by anything, and not all part of the country can use crypto in their daily lives there will be still a limitation in every thing. So country can adapt bitcoin and other crypto to their monetary system but will not replace it.
