Compared to fiat currency, Digital currencies are very powerful in-terms of control. You can control your own coin. There is no interference from the government, no one can rob it or counterfeit it. You can use it globally and expand your business internationally. I don't find anything more powerful than this! what is your thoughts on it !
Which is exactly why governments do not like them, governments are the ones in complete control with fiat currencies and they simply thought this was going to be the case forever, as if someone tried to created a centralized currency independent from the ones they print, they will simply crush it and get the people behind it in jail.
But then Satoshi found a way to do this anyway with the creation of a decentralized cryptocurrency, and since then governments have been baffled about what to do with bitcoin.
