I have an announcement to make. Flatbitcoin.com/invest is a scam run by a Coinchat member named 'yoda'. I invested .10 BTC in this supposedly risk-free investment and expected a return in 7 days, as the site's terms stated. It has now been 14 days and I have not been repaid. Yoda has not responded to my PMs on Coinchat even though he HAS been online recently, as a Coinchat mod pointed out from the logs. Stay away from Flatbitcoin at all costs.
So they offer a 5% weekly interest while claiming no risk, without any further information on what is done with the coins.
That sounds incredibly legit ^^
