In my opinion, if you have the opportunity to invest, then you should do it. But why not make a bounty campaign, all you have to do is time to perform simple actions and account on the forum or social networks. You need to try to make the most while you can earn.
I think this year's bounty campaign is very difficult, many of them don't make money, and most of the projects are scams. so I think if you start investing by expecting capital from the bounty it is not a solution
