I partially agree with Lucius. However, there are some bounties in the bounties session which may be worth.
That digital gold bounty looks interesting (i took a brief look at it and I liked it), as some other projects already on exchanges. Bounty hunters should be vigilant and know which project to choose.
There are some which pay in Eth, others with tokens that are already in exchanges.
THere isn't room for everyone in good BTC payment campaigns (sadly many spammers are still in long term good payment campaigns), but there are quite a few opportunities in the bounty session.
You are right, its incorrect to row all under one comb. Even if there is nothing interesting right now, maybe something worthwhile may come up tomorrow. It is important to maintain concentration and keep abreast in search of new interesting projects. Analysis of projects with the goal of separating grains from the chaff is a useful experience in itself.
