500000000 - 432228107 - 5000000 = 17771893 remains for payment of the bounty? And this amount will decrease every day with sales growth?
Their bounty budget is 5% of total issued tokens.
Now sold more than 435 million tokens. 435000000 x 5% = 21750000. We get 435000000 + 50000000 + 21750000 = 506750000.
So they will pay bounties from the tokens for their team or cut bounty payments. Or they will sell all tokens in general and will not pay bounty and will not leave tokens for their team.
