Thanks a lot for your answers fellows. To answer the first 2 replies I agree with your logic, but what happens when you don't have the funds to buy the coins you want to, but instead you have some equipment that can get you some?
In that case, I have to think about sacrificing my mining equipement and divert into a new phase of investment which is buying potential altcoins. I understand the underlying risk facing into a new one but have to think in a practical manner knowing that mining isn't really good at this time.
And I mean to mine with a small profit (small but profit).
In this case is ethereum the best option? I believe that yes, instead of looking for anything else. Maybe there are other coins too that can do the job. I don't know.
It gonna be the first option other than Bitcoin.
Anyway, that is too risky to invest only one coin, and having those other potential altcoins will it something to make it better and lesser risk.
You'll have something to more if you have more time in crypto and you truly understand what you are doing away from mining.
