This is one proof that we need regularization and legalization right now because without it scammer are free to do something illegal without any disciplinary action by law. If regularization and legalization will implemented scammer will going to afraid because government will have rights to make a law to punish scammers.
The question is if people will still not fight it being regulated, fine it can be legalized, but I am sure people will still have issue with its regulation, because majority of them feel that once it is being regulated by the government, they will still be able to monitor their transactions.
For me, I dont have any issue with government monitoring my transactions because I have nothing to hide, the speed cryptocurrency payments has brought solution to slow and third party involvement is more than enough for me to continue with the system for the rest of my life. So if regulating it is what it will take for these crypto scammers to be wiped off, then I am in full support of it.
