While not a direct coin scam. I can say I was scammed by Micro-BTC.com. A cloud mining company. Seemed legit. Professional looking site, annoying rules ect. Then one day, boom, money gone, and account deleted. Just hoping I can save another person from doing the same. So post it anywhere you like.
O ! about these "mining companies" - I can tell you that I published more than 50 audited companies (@mobiltema) since the middle of last year. Out of 50 pieces left 2! The rest were scammers. Beware of their activities! Work only with companies that are more than 5 years in the market.
