Based on what was happened today, payment in ethereum will be good for hunters. One more thing, dev need to pay us in weekly basis and not after the end of the ico period. But I am sure none of the project will apply it.
I certainly support the initiative of paying the bounty of ICO to bounty hunters completely in ethereum, or half in tokens. That would be very cool. And it is not necessary to pay weekly, because this will cause a lot of problems for the ICO team. It is enough to pay monthly, as is done in some ICO generosity campaigns that are paid by bitcoin. Payment in the ethereum for the ICO team has its merits and demerits. However, in general, I think that ICO teams will not agree to this.
For example, this thread is already more than half a year and yes, we know only a few projects that applied this approach during this period. But it seems to me that in general the bounty as a direction is already changing and soon we will not see really good projects with traditional bounty campaigns, only a scam will remain.
