I'm already doing something similar, the difference is I put some money to the exchange two months ago and for now, I'm using only this pool to make profits. Till now I was able to double it, which in my opinion is a great success due to the fact I'm basically a noob in the world of crypto ;)

But I like your approach also - so maybe I will try it - with one small difference - as @pibyk already said, the BTC should be changed to something else.
