I know about CEX. I'm aware of managerial issues and open source. Been a VC user for many many years. But I'm new to Crypto and I don't have much $ in there. The coins and tokens are only on the exchange as investment at this point and I fully intend to pay my taxes. Also even if they were off of CEX, at some point I would want the profits transferred to the bank. so I would have to explain how I came up with 2 mill if that's what I made
But as far as anonymity, I would never use any encryption software that's not open source. Never in a million years. Windows, MacOS, none of that can be trusted to be clean of back doors. Linux 
~snip~ If you want everything legal, then you have no choice but to play by the rules and pay taxes as defined by law. The best thing in case you have doubts is to look for a tax advisor who also understands cryptocurrencies, and such people can advise you on how to do everything the right way, and maybe how to get some tax benefits.
If you want more privacy, consider using decentralized crypto exchanges and using non-custodial wallets - and you can extract profits without paying taxes using virtual cards that can (for now) be bought for crypto, or if you have the courage by selling face-to-face. In addition, if you happen to be from Europe, you can still find physical crypto exchanges without KYC or crypto ATMs that work on a similar principle.
