WHEN THE BOUNTY END?
Bounty start from 10 June 2019 till the end of token sale.
if you look at roadmap token sale will end on January 20, 2020 (if there is no roadmap change) for more details you can ask bounty manager in the telegram
The team still has a lot of time to look for a decent exchange, not really the top 10 but a decent and trusted one that can help with IEO. Combining IEO and ICO is quite difficult but I know they will succeed.
