Electricity costs of 0,06 $/kwh are in the higher range but as bitcoin increased for some $ thousands recently you should be still fine and it's also possible that the price will increase further. Do you have to register your activity and pay fees and taxes on the winnings?
Without experience, going solo is always riskier than joining already successful projects with competent managers and probably better basic conditions like yours, but that is your decision.
No? It's perfectly viable to mine at or below electrical costs of $.10/KwH and above that is the point that's actually high. Difficulty's absolutely skyrocketing recently but you should still be okay mining at $.06/KwH. Hell most hosting facilities and colocs don't have rates like that. You're just fine.
