Not all managers Bounty, have to prioritize Escrow, because the tokens he is promoting in the bounty are not yet circulating on the market, most companies don't want to take risks, they only pay the manager who manages their rewards Most managers get paid with ETH & BTC.

Bounty participants who receive tokens after the bounty is over, not all managers are 'bad', most participants do not want to be paid by the bounty company, the manager only receives from the company and distributes it to participants.
it is a manager's risk in case of embezzlement, meaning that the manager is not committed to the company.

Escrow: applies to paid campaigns with Bitcoin or ETH, does not apply to bounties that pay with tokens.
No one who holds Escrow accepts tokens, if with Bitcoin & Ethereum many.
