I think its impossible to regulate cryptos because of their decentralized nature but it is possible to regulate other digital currencies that is not decentralized . some says that being regulated is good because they are now supervised and approved to be legal and legit but other said that being regulated is bad because this can lead to taxation and we all know that tax is the root of corruption
The government as a policy maker wants to regulate digital currencies such as bitcoin, so that taxes can be taken for the development of the country. Because taxes are a source of state funding. On the other hand, taxes are often damaged by greedy officers. In principle digital currencies cannot be regulated, but restrictions can be made that protect citizens.
