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.
