Very simple stuff. Create business, build business, accept btc and buy your own service with your own btc. Pay the small amount of tax and you have clean money. One simple method of hundreds or thousands out there.
The thing there if your business is legit? If you can easily run away by that then you simply can be a part of a money laundering scheme again. Aside from that creating a business is never been easy especially for me(or most of us here small time earners)
