Everyone on the forum knows what Bitcoin is.
Bitcoin name is the combination of 2 things i.e Bit and Coin
Bit means piece or basic unit of information in computing and digital communications.
A coin is a metal used as currency.
Therefore, Bitcoin is a basic computing information currency and that's why private keys play an important role.
will all the nations of the world use Bitcoin as a currency?
It is not possible. A country that is communist like China will find it hard to accept Bitcoin as currency.
How important will it be? It will not go to the good side to the bad side? I want to know the opinion-
Yes, it won't and the government's negative stance towards Bitcoin is the major problem we have, if the government support Bitcoin totally, I'm the Dev will find a total solution to every problem cryptocurrency is facing now.
If I'm not mistaken, it depends a lot on the region. In some places this is not a problem at all, but in some places it is quite difficult.
There are several bitcoin ATMs and bitcoin-accepting outlets that I've met, I don't know how bitcoin ATMs work, but I think this is a good idea so crypto users are more active and no longer have trouble transacting.
Bitcoin ATM is a good innovation and it is easy to use but the hike charges fees are the major problem people have with the use of Bitcoin ATM and it will be nice if something is done about this in the future.
