If only Labcoin was the only one, you can add the Ukyo/WeEx/BitFunder mess, inputs.io
These were all BLATANT scams, which only people blinded by stupid greed could fall for.
LABCOIN had the taste, the color, the shape, the smell and the sound of a scam.
Wouldn't say that for Ukyo's exchange, even though WeEx was always looming behind.
