I'll be making a post about MEME that is already staked either later today or tomorrow. I can take care of your case in the meantime.
According to your r1s2g3 steem-engine account you currently have 49726.02739728 staked + 273.97260272 unstaked. That totals 50,000.0 MEME; in an exchange of 10 steem MEME for 1 hive MEME that gives you 5,000 hive MEME.
5,000 hive MEME has been issued to your hive-engine account.
Thanks holovision, I confirm that I received the tokens.
