How much do the gas fees eat into your profits?

Around $1 to $2 per contract interaction. It eats a lot of gas, depending on how busy the network is.

How is the volatility on the interest rate?

It fluctuates daily. It can go straight from 6% to 5% each day. That's understandable because their APR depends on supply and demand. The higher the supply and the lower the borrowed amount, it will go lower, and vice versa.
