My story with BTG is funny. When it was trading at $400, it had a few flash crashes to $280-$300. So I was pinned to my desk with a limit buy order at $310 so I can dump quickly and make an instant 30% $$$. We had party that night and after 30 minutes of being in front of the computer, a friend came in and I had to go get him from the lobby of our apartment.
Long story short, more guests came and I totally forgot to cancel my limit order. The next morning, I opened up my laptop to check the prices and I noticed that I have BTG in my wallet ! Strange! then I remembered that I forgot to cancel the limit order, however it was late, BTG was trading below $300 and then I got stubborn to breakeven and wait for it to go up again and look where it is now and I lost 50% of my money in BTG.
