This topic has been raised many times, different opinions and different solutions have been expressed, but nothing has changed. Project teams don't want to change anything with payment. They benefit from the current situation, where they dictate their terms to bounty hunters. We just got the team to transfer the amount of new tokens to some managers in advance, which they undertake to pay us at the end of the bounty campaigns. However, here too, the scammers found a way out and change the name of the tokens for the completion of the ICO, and the tokens listed earlier turn out to be useless numbers.
We can only count on government regulation of this type of activity or on changes in the working conditions of such teams on this forum as a whole.
