From my understanding 43B would be dripped fed slowly to aid in arbitrage for the RSV.
However, they recently discussed a new protocol. RSR arbitrage is being changed to RSR staking. Does this change that 43B? I'm not sure.
This link should explain more in the new protocol, I just haven't found the time to watch it yet: https://www.loom.com/share/8bec1f4acbdc418884a56ad3ce3f3407
Reserve project has 2 coins, 1 stablecoin pegged to the dollar for an initial period, afterwards the value of the coin will be fully independent, made stable by algorithm. Creating a decentralized stablecoin.
Celo seems to be permanently pegged to the dollar and euro, and is more meant to be used as a means to transfer money worldwide, especially via cell phones. Basing their coin on fiat.
Hope it helps.
