This is a dangerous post with a dangerous inaccuracy. Primarily the insinuation that the Memo key is private. It is not! @SteemPowerWhale's Public Memo key is "STM7i2ZKwuyzGj4mUkJnnkMwcwpKEwVevTGSmd69r4he2nrwWk3az" which I can easily find here: https://steemd.com/@steempowerwhale

DO NOT CLICK "Show Private Key" in your wallet and use that Memo in your Bittrex/Poloniex transfers. I believe that may reveal your private key to the world, which is NOT what you want to do! Please, please, please use your public key, not your private key.

This post distressed me so much, I wrote and posted the following up-to-date guide (this one's screenshots are out of date) which does not make the critical mistake of this post: https://steemit.com/steemit/@hansmast/introduction-and-answers-to-common-questions-how-to-transfer-steem-from-exchanges-binance-bittrex-etc-to-your-steemit-wallet
