I urge you to look at the @bittrex wallet. https://steemit.com/@bittrex/transfers

There are hundreds of transfers of steem to a previously unused account called @deepcrypto8.

There are some steem transfers to a few other previously unused accounts.

I can’t see any transfers of steem to any active users, except one called @laguia who received 45 steem from @bittrex 11 hours ago. 9 hours ago @laguia transferred 170 steem to @deepcrypto8.

This seems odd.

Edit: according to a comment from @penguinpablo “Binance uses this account: @deepcrypto8
https://steemblockexplorer.com/@deepcrypto8”.

It still seems odd that bittrex is making so many transfers to a rival exchange, but none to active steemit users.
