I had plenty of stories a few months back, unfortunately I decided to hold on a bit too long, so not quite so successful now. Probably just about breaking even at the moment, but still optimistic of the long term prospects, just wish I'd sold a chunk and bought back in again. Haven't participated in any since February, as most seem to be listing on exchanges at below their ICO price. Most successful one has probably been Icon, but was a lot happier with the proceeds back in January.
