This is interesting could be a mass following with this. South Korea is preparing to Tax bitcoin use after the cryptocurrency's trading volume sky-rocked. This could spark a new trend s everyone battels to see how to control the life of cryptocurrency's
It is possible to happen if it regulated and mandatory demand by the government. Taking South Korea for crypto currencies taxes, is their options to generate income from large and fast growing currency today. And we don't know if other countries will follow then, but it is just an initial information, we need final confirmation for its execution towards crypto.
I dont think so that bitcoin may be regulated by any government because by feature bitcoin is decentralized cryptocurrency so in this regard imposing tax on bitcoin is impossible but in way government can collect tax from bitcoin earning when government impose tax on exchanges where bitcoin exchange into fiat.
It will be in favor of government to accept bitcoin being a legal currency in the country and then collect taxes from exchanges.
