When I dug into the BitConnect Bitcoin blockchain I saw things that were similar. Since BitConnect is a Ponzi Scheme; and they want to hide that fact they do a great deal of "tumbling" of Bitcoin. Each customers bitcoins was spun out daily to an individual address, and about 5-10 temporary fake (confusion causing) addresses were created for each round of payouts, then they all went back into pot for the next round. This happened constantly, which made tracking it down exceedingly difficult. I also saw similar things on the exchanges. I detail one here. https://steemit.com/ico/@cryptick/how-to-fake-a-top-100-alt-coin-chart
