I have an idea for a while and I know it could be done easily, but my question is if it's worth it.
That you create a program that check whattomine current profit coin and mine that coin and check it X amount of time so that if a different coin is more profitable then switch to that coin.
please give me your thoughts
why you want to mine the coin which gives RIGHT NOW the best profit?
till you have something mined to sell it might be dropped already and then you have mined with many others who go for "best" coin (so less outcome anyway for you due to rising difficulty).
You need huge mining power that you can farm like that within few hours like nicehash can do.
