Yes, so if someone buys 1000 ORB from an exchange, it's in their interests to send 20 ORB to themselves, 50 times? Rather than just leave it as a 1000 lump?
Yes, for maximum profit better split to 20-50 coins chunks.
Current wallet software could handle it automatically but it will take more time:
Each time PoS block is generated wallet check how old was input which generate this block.
And if age < maximum staking age (for Orbitcoin maximum age = 20 days while minimum age = 5 days) considers that this input was too large/above optimal size (for the current network PoS difficulty), and divides it by 2.
Ie 1000 coins sent in single transaction after the first finding of the PoS block (it will be on the 6th day - such large inputs generates PoS blocks very fast after reaching minimal staking age) will be split into two transactions of ~500 coins each. Or more precisely (1000 + 1 + tx fees if any) / 2 = 500.5 (+fees/2)
After this new 2 inputs(formed auto by wallet) found own PoS blocks (it near 10-12 days from original transaction) it will be split to 4 inputs (500.5+1)/2 = 250.75 coins each
And so on - until wallet split all incoming transaction into pieces of optimal size for current network difficulty (it is within range from 20 to 50 coins now, but can be higher if diff grows up enough)
So after some time all wallets used for active staking(PoS mining) ends in near same conditions and rate of PoS generations in long term depends only on total amount of coins in wallet, current PoS network difficulty and amount of time wallet running online staking - not matter if person just put coins by one large transaction or split to many small manually.
But at starting period (first few weeks) manually prepared wallet will generate more blocks(and coins to - because PoS reward in ORB is fixed, not % as it set in almost all other PoS coins).
Do I need to break my wrist and split it up 250 different ways?
