This is what i do, i joined signature campaign paid via bitcoin and i do bounties like facebook and twitter bounties paid via altcoins or tokens, the payout came from btc based signature campaign is to buy some cheap altcoins, hold it for a certain period of time until the desired target profit is reach then sell out. Same with the the bounties, the payout is hold that tokens or coins then sell out when the desired target price is reached but you have to wait for more than a month or 2. So both working and trading is what i did for additional income aside from my main job.
