What's the catch with the miner?

I've had my M2 Pro up and running for two days now, and I'm getting approx $10 - $15 per day as expected.

This might be a silly question, but I'm struggling to understand the catch here? Is it too good to be true that I'm receiving this income every day for doing nothing?

Not to mention that on top of that, I could soon mine BTC.

The downsides that I'm aware of: - the miner is expensive - your mining performance goes down if you withdraw. (But it will slowly go back up anyway) - the value of the coin could go down over time (but that just means it takes more time to break ROI)

Anything else? I guess I'm surprised there isn't more hype around this project and sub considering how exciting the project is. It seems quiet, which is fine but I'm trying to figure if I'm missing something.

Maybe it's the case that it is indeed an amazing project it's just that people don't know about it yet!
