On the other hand, the skepticism in this forum (albeit from people who are far more knowledgeable about crypto currencies and markets than me) makes me feel like I should 1) sell it all, or 2) sell only enough to recoup my initial investment.
Either way, the money I put into it was just fun money and wouldn't hurt if I lost it. It's a bit of a thrill to watch an asset appreciate in value that much within such a small period of time. The ultimate question is when to realize the gain or the loss.
Humans have a distinct disposition wherein we tend to sell gaining assets earlier than we sell losing ones (the disposition effect), even in circumstances where it's detrimental to us. Is this playing out in my mind right now?
