Please rephrase your title its misleading based on other comments they are not agree on your top list so better change the title to "my top bounty managers" I only agree on yahoo, sylon, and olcaytu2005 are one of the top here but others I cant say for now many more experienced and trusted managers are not listed like needmoney, colorlessK, deadley and many more..
1) Needmoney is also a part of TOKENSUITE team, their channel & website are already mentioned in the list. So I forget it, i can add it now.
2) ColorlessK is from Bountyhive.io platform. He is making announcements here and conducting all of his bounty in bountyhive platform, so I didn't added him in this list.
3) Deadley is recommended by few members here too, so I am collecting further information and will added in the list soon.
Further I am always welcome everyone to share your experiences with bounty managers, so that we can create a good list of BM/CM.
