I think this is a fair and reasonable proposal and the amount is realistic - I would vote in favor of this in the council.
Until the Collator Cycle proposal is implemented on Altair as well (automatic payment of rewards from the Altair Treasury), the monthly collator rewards will be made as individual Treasury Proposal.
Yes, I think this is a very good idea @Ilhan. We obviously don’t know how the market is going to behave the coming months, but I would personally suggest to review the amount again in around 4 months time.
