Are you sure your calculations can be used today? Because when bounty started, there were less circulating BFG token than they are today.
And these "$10 = 325 BFG(TRX) + 325 BFG(BTC)" are calculations based on bounty budget.
I really dont know how to calculate exact price, because "demand and supply" must be used in calculation. Will there really be a demand on BFG tokens, as daily staking gives less and less rewards.
Of course, I'm speculating just like all the others, we can only have the true picture and the real price when BFG is finally listed, the supply and demand will have an impact on the price, if we are to maintain the staking rewards we need to find ways to increase your token, once listed in the market, we'll have another option to increase our BFG token.
