As many people seem to struggle with depositing Steem back from an exchange, here is a little tutorial
1.) Go to your exchange of choice and click withdraw, a window like this will appear:
2.) Enter the amount you want to sent to steemit, try a little amount first (something 1-10 Steems)
3.) It will ask you for your MEMO -> go to your Steemit account and click on Permissions you will find your MEMO there (dont click on show, just use the public memo)
4.) It will ask for your Adress -> click on Wallet
In my case knozaki2015 is my withdraw adress!
Fill out the 3 fields (Walletadress, Memo, amount) and send !
Hope this helps!
Only send a test amount first !!
