min stake age 10 minutes
coinbase maturity 40 blocks(minutes)
fixed 2 coin reward/block
10 minutes
that's impressive
how about OPEN 'osc' stakes in 365 days
I am starting to not like +2-3days min time. Best POS seem to be these faster min. hold time. You open them up daily, sync, stake, and move on to the next thing you need to do with your PC. It get's habitual and insures lots of nodes in the network, problem/tradeoff is they only ping in then drop off after awhile.
The +2days min hold time 'stakers' can start to have lots of different chunks of coins and get consistent rewards, but this seems to limit the network to a few big fish, and small stake holders find it difficult to catch rewards. For coins like this I just wait months before attempting to stake (heavy weight) but I contribute little to the network with this method.
