What might be worth looking at are VPS services with free trial.
Yes, I was meaning this. To have free access to one or more VPS services. So, let us calculate with positive amounts only. Would that worth in a foresee-able time with any altcoin?

It could be either GPU or CPU mining.
Also, if it did not worth at all, why would be software such as Adylkuzz?
