Hey, sorry to hear about the predicament, when business collides with insane regulations, it's a very frustrating thing to be caught in.

number 2, btc mining environmental impact, I generally disagree,but I can understand the argument, however ...

number 1, the crypto exposure aspect

   a) what prevents your from selling the BTC the moment you mine them to pay for OPEX, and then invest what is leftover in tradfi?

   b) While many on this site will violently and deeply disagree in spite of being proven wrong over and over and over again (the definition of insanity, etc...), I'd argue that being "over-exposed to BTC" over the last 15 years has not exactly been a bad thing if you can stomach the volatility.
