Would banks and governments actively work and implement countermeasures to undermine this process? Are the underestimating the potential of cryptocurrencies by investing in some of them?
Do you think there is a possibility of cryptocurrencies being banned in the future for the reason of being a threat to "normal" currencies?
Nope not gonna happen even for centuries. This is called cryptocurrencies, it s.anpnymous hard to tracked maybe cant be. If it were to happen it would be absird and pure idiocy. All crypto's cant overtake any real/state currency but the price however it has the legality and full potential to be spend.
It cannot really happen as of today since not all countries accept bitcoin so there is no tendency yet that it gonna happen, not this time maybe if it will happen after more than 5 decades when many cryptocurrencies were finally adapt by countries.
it could be done as time goes by , the problem are how much time it will cost? a lot of time of course , just look at internet where 20 years ago it is something that most people confused about , we think will never have reach internet era.
and then we have recognized internet as a primary needs in the last 5 years. the potential are there but not for soon.
Goverments can restrict people
