Rewards will be pulled up to match the new bocktime
Not sure yet though
5 minutes are quite long, but 3 minutes seem to be ok.
how about two minutes? would halfen the future chain but still be very fast (in relation to a famous coin ), if you ask me.
In reality, those 2 minutes, are not 2 minutes most of the time, but a little less... So I think 3 minutes would be best...
Basicly, a transaction is instantly credited into your wallet if you send coins, then its just a matter of confirms before it becomes spendable... With the path we are taking now with CHIP, confirm speed is not really priority... Minted Blocks already confirm after 8 blocks , so if we take a 3 minute block spacing, your coins are spendable again within 30 minutes, which is still a hell of a lot faster then most of the coins around
