Sometimes I also encounter some unsuccessful bounty scam or bounty. It took me a lot of work. I had some experience following to pick the good bounty:
How are good bounty?
Its not Scam project
The rules of the bounty must be easy to do
How to Choose Good Bounty?
That bounty gets many high Rank in Bitcointalk join
You can go to the spreadsheet (Total Bounty Participant) to find out. Because of the high rankings on the cast they are experienced.
The project is highly rated on the ICO Rating websites such as icobenh, icorating, icomarks etc.
Because they do not have that ICO on such sites
Bounty manager must be professional and Prestige is trusted by many people
Because only the person who decides to send the token to you. A Bounty Manager fuzzy chicken open fat even when the project is successful but the Bounty Manager is bad to send Token to you, you only have the way "Waking in the night".
AmaZix, ColorlessK, Sylon 3 are very reputable and professional Bounty managers you can find them if you want.
How many bounty do you have at once?
It does not matter how many bounty you have at the same time. The important thing is "How much money do you get at the same time?"
Because this is a mixed play mixed with many things you have to know what is valuable.
Every bounty I do, I eat a lot. Actually do a lot of eating but do the Bounty of Good Projects you get Token.
Why ? As it succeeds ICO has the money that pays you. If it fails then 100% you do not receive any Dong.
