Worst Altcoin ever ?

Hi Steemian,

Let's talk in this thread about your worst altcoin trading/investing experience ever?

I had a pretty good ride with Altcoins, nothing much to disappointment. But the only coin that made me regret investing was Syndicate (SYNX). I invested in it without going into much details and what was even worst that I bought it at the highest price in it's history. I think it was worth 27k Satoshi back then. I was stuck in it for almost a month until I decided to cash out with loss.

What was your experience?
