My suggestion would be to opt out of energy waste for more efficient and less power consumptive means for nailing gains. If ure looking to churn out a few dollars at this very moment u can do it thru mining but better start earning ur way up via investing in alts. U will go slow at first, playing with lesser amounts will guide u thru trading tips and tricks (there are many, which makes professionals learn 10-20 years before they advance their asses high enough to be able to retire under 35, if they dont commit suicide). By learning the basic principles of risk management, u will probably make a lil bit more than what u expect from mining alts. Trades will go better and easier. If u wanna get used to this sapce, u can mine for a little while and, when u are ready, switch to trading. 0.5 $ or 50 $ a day is far from close to what a dilettante schoolboy makes in average on a fewer % of their total trades.
