My best pick is Campaign, if you're lucky and get a good bounty to work on the pay is quite good also I like trading to but am not very good at that, don't have the patience to wait
But that is the problem with bounty campaigns, you are relying on your luck, you are hoping that you are going to select the right ico at the right time and while this was relatively easy during 2017 now it is a lot harder, even now that the price of bitcoin has recovered during the last months people are still not investing in icos, many people have lost everything they invested in those coins and they are not going to forget it, at least I wont.
And any new investors that could be interested in doing so are going to be warned by people in the forum and other websites that is not such a good idea, so the future of bounty campaigns looks dire in my opinion.
There is room for a lot of new investors and ICOs will never die. It isn't luck either, if you put in the time and research you can still find projects that give you 100x return on your initial investment.
I'm not giving up on altcoins and I'm always on the hunt for new and exciting projects that peak my interest.
