People would only need to be careful same way we are being careful with fiat also, because fiat system is the worst when it to scam rate, and we still have many people that still has not got burnt, the way we are careful is also the way we will be careful with crypto investment also. All these are there because it is still a very young system, and as we continue to move further into more development, there will be so many things that will be put in place to control this.
We have already had the implementation of kyc which is already doing its own work, and sooner than later, as government are beginning to accept crypto now, they will also come up with series of idea that would control the misuse of the cryptocurrency for illegal purposes and these figures will reduce.
Government to control cryptocurrency? Lol are you serious supporting this? Sounds like it's against satoshi vision .. it's obviously against cryptocurrency vision itself that supposed to be remain decentralized, this kind crime issues, abusing the cryptocurrency technology is something really normal to bring up to the public as an effort for those who don't like cryptocurrency become a mainstream thing.
Ignore this kind issue and stop beating around the Bush guys...
These guys from the government are constantly trying to rake up the crypto for themselves. People do not need a centralized cryptocurrency.
