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?
Until strong regulation and taxation policy by governments, It is not possible for cryptocurrencies to become mainstream payment system, Bitcoin is decentralized and it can not be controlled by single entity, Corrupt governments will not allow decentralized payment system, They may create their own crypto currencies.
