yes I agree if bounty hunter is paid using USDT, that will keep price at market because bounty hunters will not sell at very cheap price, but it's impossible if they will pay bounty participants using USDT
Maybe teams will take their job a further and decide to accept other forms of cryptocurrencies as the payment method of bounty distribution in the future. Paying to bounty hunters in USDT will not help to prevent the dumping of new tokens after the listing.
