Unfortunately, scammers are very difficult to track and we cannot or find difficulties when reporting this crypto scam to the police.
The ways are by getting ourselves to be more aware of the characteristics of scam projects or investments. We must increase our knowledge and not desired with high profits that is too good to be true
Even if we had the facility to report scams to the police in any country, it wouldn't matter much and it wouldn't change a thing. There is no global regulation, neither at a continental level, nor by country, so even if we reported a scam, nothing would happen, since the scammers could be acting from another country or from another continent. For that it would be necessary to have a global regulation, and that will never happen, as always, each country wants to be above the others.
