Maybe PAXOS is the best option for hackers or other evil deeds because PAXOS is a pretty good stable coin on CoinMarketCap's top 100 radar.
If these criminals are looking for a way to make transactions using Tether then that is not good because this Tether tends to be clean after the ultimatum of 2017.
So, PAXOS cannot refuse to work from criminals because PAXOS is used for stable cryptocurrency.
