I was going to say the same thing. Could Bots still buy and Sell their own positions? They are all small amounts and about the same too. This is the only thing I can think of, but even then it wouldn't post in a wallet.
Two 10,000 volume sells right before the wallet disabled too. Insider trade for sure...
Trades can still take place. Doesn't necessarily mean it's insider trading I have a few SLR left on bittrex and i'm sure not everyone has withdrawn their slr before block 830000 even tough that would have been the smart move to stake...
Some people might have been unaware of the POST update and hence still have their slr on bittrex
but who knows
