I think mine is the most profitable because it is certain every day we get and we take pains to spin our brains, although must have a large capital cukuo.
currently I have not mine because I do not have enough capital, maybe a year or two more I will start mining because I see we are more comfortable to mine than work.
That is bit strange though, I mean, is it not getting tougher day by day to do mining? So, 1-2 years will be too much I believe. Anyhow, let see how it works.
I am not mining as I do not have much patience to wait for returns. My friends are doing it though and they are doing good.
But what's your take on using what I mentioned above, as it just runs in the background not requiring you to make any effort.
