A lot of them seem unreliable or even full of ****, sometimes just by checking the site you get a feeling that it's probably some type of fraud going on there...

The reason I'm asking is because some altcoins seem to be quite profitable compared to $6/year from Litecoins on my machine, and that's 24/7, meaning more like $2 a year if I keep it on only while I sleep.

Anyway, I'm just considering to consider altcoins, but fear it may be a waste of time and intense frustration at some point, and having loud fans running loud half a meter away from me isn't that pleasant, while sleeping or otherwise.

Any help is appreciated...
