Bitcoin is a very good thing to have as an asset. Just like gold. Even better if I may say. It's secure, and unlike fiat money it actually exists and work is put into it to produce it. This makes it great to store value.
However, it cannot and will not replace current fiat money that the entire world it using. It just cannot.
actually bitcoin is not that secure. we can see how many people were hacked.
alright, the point is both bitcoin and fiat is not really secure. they have their own good side and bad side. however I agree with your statement. bitcoin will not change fiat totally, but in some cases we can buy stuff by bitcoin.
Well its laying at themselves, they can secure it by themselves and if they are not doing this on a right way you can get hacked indeed..
