Hi,

 I know if you can get your hands on some great gpu drivers and start mining today you can mine eth or anything you seem to like and make some return hopefully.

 But what I wanted to ask is different. Say you got your hands on 100 radeon rx480 , you set it up, its running and everything seems perfect so far.

 What if eth gets too difficult? Which it will, what if eth goes down , which I don't think will happen, there are many stuff.


 What my question is this;

 What if I get my hands on 100 graphic cards like radeon rx480, however, I decide to not mine eth but mine through a pool that is multi algo and multi coin, just use the best algo at that exact moment to mine the optimum profitable coin. Is there pools like that anymore? Can I do that? Just mine whatever is most profitable at that moment and realize the profits?

 If I get 100 radeon rx480 , will I be able to make money with it for a while or is it just 1-2 years at most? I would like to heavily invest in this but I would like to get the initial investment back before I consider reinvesting and getting more or replacing.


tl;dr : Can I use current good graphic cards to mine coins now or future coins or whatever is most profitable and make money for 5 or so years even maybe more?
