I have been using PM for ten years. It is a very stable e-wallet with an interest rate of 3.5% per thousand per month. But it seems that it is relatively conservative and lacks innovation. The website structure has not changed for ten years.
When you say this do you mean:criminal activity
This is somewhat correct. PerfectMoney become popular in 2013 after feds shut down LibertyReserve which was mainly used for money laundering and criminal activities, as it's replacement. They tried to show to public that's not the case by blocking suspicious accounts etc, but everyone knows what they are doing. Not sure how they survived all these years. I also woudn't recommend you using this service for any business.Perfectmoney is for criminal activity and not to used for some serious business.
