I`m not satisfied in my bounty reward this year because I cant saw a good project who are paying their participants with high reward even you did what is the task there.
When the prices are too low you only get very small amount when you convert your rewards into fiat, most of the bounty paid their participants with there tokens in 2018, but most of them don't have any real value yet so if you are waiting for good bounty then join only on the signature campaign with bitcoin payment.
But it's very difficult to get into such a campaign. They are mostly reserved for high ranks and require posts in Gambling section where I have completely no experience to make contributing comments. But rewards in such campaigns are awesome and if you can get into it you will always have a decent profit.
Most ICO projects have problems to reach softcap and this affects also bounty allocations in a bad way.
