The government making way to regulate the spread of cryptocurrency as many claims that they have heard about scamming issues. I may think this the best solution to minimize the level of scamming but somehow we don't want also to be controlled by the government as we wanted not to involve in corruption. If the regulation may not take place, we can't also think that we can stop these frauds and scamming issues.
Yes i read some news that other country prohibit bitcoin or any kind of cryptocurrench in their country, i didn't if this crypto threatened their economic groth or something. Here in my country they didn't announced it is scam nor prohibit this cryptocurrency but they didn't encourage people to get engaged in it due to scammers invasion may possible well i guess its because of being decentralised of cryptocurrency.
It could possibly some sort of personal interest that makes them prohibit the wide growth or Bitcoin adoption. Tax is one reason that makes them decided to do against crypto and they like to regulate in order for them to force every crypto holder to pay their individual taxes.
Definitely, they can do nothing to stop scams and frauds because it needs the participation of everyone and I know that we/they can't simply put action with that easier as it takes. Scammers will find their way and keep unnoticed by the authorities.
