I'm looking to sell ~8 GB and ~12 GBB, if anyone has bitcoins on ydx.slack.com then I can set ASK orders at 3 microBTC per 1 MB(B), it's with 25% discount comparing to the market price, if I'm not mistaken. Or I can send an invite, I'll need your email for that. All trades are escrowed by Yassin on that Slack. Read the rules on http://iotasupport.com/buyingiotaotc.shtml, most important part is that he charges 1% for deposits/withdrawals.

SatoNatomato, time to show your loyalty, it's very cheap GBs for you.

EDIT: I miscalculated, it's 33% discount.
