Should I mine ETH as well as buy BTC

Hello

I see this gets asked a bit and circumstance really navigates which way to go but I always think about it.

​

I currently have a1080FE running 24/7 doing nicehash.

I run my RTX titan when I'm not using it also on a nicehash on a seperate machine.

​

I buy bitcoin anyways every month with fiat also.

​

Would it be worth just having my 1080 mine ethereum with flexpool with Trex 24/7 and just using my titan as i am now when not gaming?
