I can't see any direct transfer or anything between magicdice's accounts and powerguy that would not be bets, referral or dividends claims.

But I found that Hive account@powerguy is owner of these accounts: Hive account@assassinss, Hive account@crypto-miner, Hive account@dice-dice, Hive account@diceking, Hive account@kingdice, Hive account@powerguy, Hive account@steem-nice, Hive account@steem-steem.

So it really stinks... those accounts were the biggest wagerrers.. so Hive account@powerguy was 'mining' the tokens all the time, not just in the beginning. What is interesting that Hive account@powerguy received transactions through binance (screenshot below), although he uses upbit. I like the memo of these txs.
