Harmony has a good bounty campaign but the team decided to close the bounty campaign following the agreement with Binance. It can be the best upcoming IEO too..
Harmony was indeed a very surprising project, at first they did ICO, but because of its very good development and then they did the IEO at Binance, this was a very great thing.
I think most people underestimate Harmony project and the last thing they expect was the project getting listed on Binance for IEO which change the whole story, most IEO projects are not interested in bounties only the ones listed on second and third tiers exchanges
