I have no stake in crypto besides a bit of eth. 2 coinbase examples. First: your deposits are covered only if they're denominated in USD. Second example was the fine print on Coinbase's crypto-loan thing where they said they're giving custody to a 3rd party and giving you all the risk. Good luck on that APY!
A free third example is all of these "APY" and yield-farming things in defi (usually) project figures based on a couple of early whales moving into a shitcoin, getting random people into it, then swapping liquidity to the next one. The initial move isn't exactly a lie, but assuming the next 6-18 months will sustain the advertised number is (imo) quite deceitful. Now you get to "stake" and lock yourself in for months! Yikes. That's on top of liquidity vanishing in a crisis.
tl;dr the nuance on this stuff is detailed, and the details are important in times of crisis
Can you link me to these instructions?
