10$ a day isn't practical at all for investment or online purchases. It's only good if you have a big rig of those to get at least 1,000$/month, but at what electricity and noise cost? I don't think I can run that in a single bedroom apartment with neighbors around.

Bisq sounds interesting, but I have my doubts about them, since there is no escrow system and I don't think there is enough liquidity either. I'll check it out anyway.
