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.
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.
Every day a lot of people gets their fiat robbed but you can't blame the government for that (or whoever made fiat). You can't say that paper money isn't secure because you got robbed.
Its our stupidity, thats the reason why we got robbed. Its not a sin being stupid its just that we havent done our research and understand how online business works including how bitcoin investments and how to protect ourselves. But after being hacked and robbed we still being a victim until now then it already our fault. To avoid being hacked or being scammed we must do some research, ask some professionals and technical persons specialized in bitcoin as to how to protect ourselves from this attacker. If we engage in bitcoin we must not be lazy and wait for the day that we ourselves becomes victim.
Soon fiat virtual currency will launch and it will become more harder for bitcoin to replace fiat . But since fiat is going digital it will also be prone to hack attacks. So we must be wary and do some precautions to protect our wallet.
