How mature do the coins have to be before they start to stake. And is is really 50% interest every year?
Min 9 days before the coins starts to stake. And yes it's 50%year.
once total coins reach 1.5 million it is 25%
estimated 6 months away
u dont have to keep wallet open all the time
open it once or twice a month for 2 days is enough
coins gather coin age offline too
just u need to be online and in minting mode to compete for minting a block
once successful minted u convert all coin age of that coin pile into POS rewards
POS reward will be coins*age/365/2
example 1000 cons age 30 days
1000*30/365/2=41.1 DMD
once we reach total coins 1500000 the2 will become a4 (50% become 25%)
so if u buy 1000 DMD now they become in 6 months 1250
and that 1250 will at the 25% stage which last a few years ear u each month ~ 25 DMD
some people say once we reach 25% POS stage lot people will lose interest
i dont think so because one of the things that affect the longterm increasing value is the constant decreasing inflation
and earning with the 1000 DMD u bought today now 40+ DMD a month
and if u keep earnings later on 25 DMD a month is still great value gain
