I was one of them. But I traded myself out of loses with other coins and even made profits. Of course, I was a bit angry with the AMP price crash. But I liked the project before I lost money and I liked it after I lost money. At least now we have a concrete view of what they will bring out and I think this can be huge. Social media projects are very profitable. Look at Steemit's surge or Reddcoin. Don't underestimate AMP.
