Bitcoin is touted as a new miracle in this century, it has become an alternative to complement the needs of financial transactions at the global level now, Bitcoin can then be said to have succeeded in establishing itself as a universal currency, because we can say that Bitcoin is very qualified as a money because it is durable, rare, shareable, and recognizable, Bitcoin became the currency of the virtual world on its way Bitcoin (BTC) transactions exploded and shocked. The product is selling well and becoming a prestige of individual wealth in the international world, however, many are pessimistic that Bitcoin will be able to shift conventional currencies both at the local and global level, will there be a miracle of bitcoin to shift conventional currencies
Your points about Bitcoin are valid and actually true, Bitcoin has grown to be the best cryptocurrency today because it solves the issues limiting people to carryout various transactions easy, cheap and fast, unlike going to the financial institutions where you will wait for hours, with Bitcoin a payment can be done easily from your own comfort place.
Secondly, I don't think and have not buy the idea that Bitcoin will one day shift or replace conventional currencies (that is fiat), the world government will not even buy into the idea.
Thirdly it is my own understanding that Bitcoin will fill in the gaps or lapses created by fiat monetary system, it will work alongside with fiat to make payments easy and fast, it will solve the issues which has limited a lot of people to access certain financial services freely without any intermediaries, and the list continues.
