I bought a chunk of Ripple back int 2013 and tried the trading platform for a couple of months. People were creating currencies and trading them for bitcoin. Fun at first. I did not stay because there were times when I could not sell a position, but only a portion of my holdings.

I was told that I had to find the creator of X currency or the other creator of Y currency in order to sell out my holdings in that currency, to essentially "undo" the trade I had made months earlier. Complete insanity. So that is when I quit.
