LOL, everyone is into evading taxes. If you can earn 10x, 100x return on your investment in cryptos then why the hesitation to pay taxes. I know tax money is wasted a lot, but not paying taxes altogether is not the solution. If you are rich, just pay your taxes and be  in a safe zone.
*OP not trying to belittle your service, just my POV. Of course, most crypto investors would like such kind of services, if they can avoid big amount of taxes without getting into trouble.
