Personally the money laundering stuff with crypto is nonsense. All you have to do is look at all the big banks laundering money in the news and just one or two banks will surpass the amount of illegal money in crypto (Deutsche bank is an example).
Definitely quite a good informative post about BTC and the taxes. As long as you aren't breaking the law, I see no reason to worry. At least in the US, we only need to report the amount of income earned. You are also allowed to take losses out. The only thing I am confused about is whether or not selling out of a lost and buying back in will work as an argument. At least in the stock market, you need to wait for a period of time before buying back in for it to count.
