Sorry, I was logged into the wrong account. Yes, I work for Blockchain.info and rejected this API key request. I wanted to post here to let people know that this is clearly a scam site.
Well that's sad though its expected to happen, fortunately I got almost of my investment which is not bad
( I invested 0.04 btc and got roughly 0.035 btc). This site have a potential to gain more "greedy" investors cuz of the attractive hourly payment but they ran away too early. Bad luck to those who haven't got at least half of their investment.
