The "right" regulations would be all the new rules that remove the anonymousy of btc transactions.
"Know your customer" policies and ID verifications would become mandatory for all online bitcoin wallet services and all exchange platforms.The harder for criminals to stay anonymous ,the better for the bitcoin community.I know that a lot of crypto supporters hate the KYC regulations,but there`s no other way to reduce the crimes and fraudulent activities with btc involved.
oh the famous "bitcoin is used for illegal acivities" story
KYC regulations doesn't do much in terms of reducing crimes! a criminal will always find always to circumvent this
fraudulent activities involving bitcoins or any other , even anonymous crypta is dwarfed by fiat fraudulent activities
the figures are simply incomparable, millions of times more , but all we hear is how bitcoins is used to extort someone
or drugs are bought for bitcoins etc. , you seriously think that it is anything more than a PR against cryptocurrencies
finally, have a look at the total money supply infographics and think, what is used the most for criminal activities
