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.
Honestly, what most people should understand is that all you need with campaigns are just the resources you have built over time to earn something substantial as a passive income and enable you to hold for the long run some of these coins including bitcoin which could give you some profit in the long run.
Trading is more of full time thing if you want to get the best out of it and for someone who is basically not ready, it is better they just build what they have and earn something good later on.
I would advise if you do not have any knowledge about trading, then do not even bother yourself much about it until you learn. It takes a lot and you cannot at all compare it to campaigns. Campaigns are just some pretty easy way to earn some bucks and if you can hit a good project, you can always get the best from campaigns. Trading is cool to make some good cash, but not as easy as it looks when compared to campaigns.
