Renting my Rig out. But whyyyy?

I’ve rented my rig out for about 15-20% more than what I could mine directly for. But why are people renting my hash at this rate?

Renting my rig to mine a coin still costs less than buying the coin from Coinbase. Is that why?

Depending on the coin.
What’s the numbers?

I haven’t found a single coin that you cloud mine that gives you more coin than you paid for.

But I did find that if you want 1 LTC it will cost you less to have someone mine it for you than buy it from Coinbase as an example. You can arbitrage it.
