Reality Check On Coinbase and Nicehash

US based here. Lots of negative posts on the reddits (rightfully so) on Nicehash's new spontaneous policies, including KYC requirements. And Coinbase as well.

So are they really that bad? Assuming no increases in taxes, whats wrong with the KYC (ideal idea i know. taxes going wrongfully up on crypto)? If you mine with Nicehash everyday… whats the problem?

Coinbase… is it really that unreliable and unsafe of a hot wallet? (obviously cold ones might be more secure, theoretically). im just … wondering where do we go now if CB is rly that bad (and binance us is no longer exchanging for USD)?
