Might be my lack of understanding but something looks very dodgy with the master nodes to me.
Looks to me like masternode stakes are being recycled and getting multiple payments.
Look at block 7534503.
10000 qrk removed from a wallet that was and continues to receive masternode payments.
That 10k is moved along with 15 more 10k chunks to another wallet in a 160k move.
Then 175k is moved on December 31st in block 7549438
That 175k is then broken back into 10k chunks and are now receiving additional masternode payments as of the 1st of Jan.
Can someone with a bit more tech savvy look into this and let me know your thoughts? Hopefully Im wrong.
