@BRA_16-D price fluctuations are unfortunate, more-so with this major dip. As this funding for a bounty, it would remain in the treasury's custody and be drawn down on a monthly basis at the EMA rate at the time. With dips like this it reduces the period the bounty can operate, however, if there are better rates (in the future) it can extend the bounty's coverage.
Imo, it is only fair to receive the funds as-is, utilize it on a monthly basis and when the bounty has ~2 months funding left we'll engage for a top-up then.
@Birdo 🐥 if I recall correctly, the recommended number of collators came as a suggestion from SRLabs (relayed to us via Joe W3F). The reward of $300/mth was calculated based on analysis of market costs which I still believe are valid today. As these are live chains many participants maintain some semblance of backup to ensure livliness and also to maintain their spot.
The reward isn't meant to only cover expenses but also be fairly attractive to ensure slots are filled. We have experimented with no reward and the results were dismal.
