I'm asking you to mine 50 POW blocks. I guess if you want to wait it's not that important, but it would be good to have a regularly moving chain. It doesn't seem like inputs are being split so people have to send coins to different addresses or even the same address. If there are 5 wallets staking, each wallet needs more than 10 inputs to keep the chain moving. You should send your 9% to a number of addresses so you will have many inputs to stake with.
