After the 13 years are up and we are at 1 million coins what will the POS reward rate? My understanding is at that point it will be based solely on transaction fees.
I know that might be a hard question to answer but can you give a ball park guess?
Thank you

It will all depend on the amount of transactions and fee settings each person chooses but the full amount of Bitcoinplus have not been mined into existence yet so nobody can predict what the adoption rate will be in the end.
