Have you been audited by the IRS? Do you know their tactics? I can tell you from experience that that if you use bitcoin, then you must use it their way, without privacy tools. If you intend to pay your capital gains, which is for every kyc coined tx, and you use these 'tools', then you will get rekt. Any coin going out that they can't trace is treated as a capital gain, and any coin going in is income.

It all starts with a simple letter.

If you want privacy and pay your taxes then too bad. It's privacy + tax evasion == crimal OR transparency + KYC == IRS wins
