as time goes by there is a lot of new motives behind any commited cybercrimes , cryptocurrency that born since 2008 become a primadonna for those who have abusive behavior like scamming on behalf bitcoin , phising etc.
a lot of techniques making fraudlent in this digital financial era and i believe every country in this world even the poorest country are aware about the issue and have taken action against all of it , still they can not handle it 100% , they only human.
cryptocurrency is a free world , nobody can protect you 100% not even police , educate yourself that is the better protection.
