Then i don't understand how it works, but later i find out how it works with Hive account@airhawk-exchange, after you transfer to Hive account@airhawk-exchange you will then go to there telegram account and you will see buyers like Hive account@smithmadu etc just write write amount of steem you want to sell and negotiate price with the buyer than you will write in the telegram that let Hive account@airhawk-exchange release the steem to the buyer and you mention the buyer's name... Final.. thank me later..
