Let me give you my experience: people begged me to get into bitcoin when it was a couple of $. It just didn't sound interesting to me so I ignored it. Did I miss out? Yes, but MAYBE a few hundred $. I would have sold at 50 and I would have absolutely sold at 100$, get a nice phone and that's that. In no scenario would I have bought at 5 and hold on to it until it was 40k.

Not to mention that the entire argument is based on a get rich quick scheme which is exactly what the doubters argue crypto coins are, and the entire post which I replied to originally can be summed up to 50Cent "You just jealous cause I'm rich".
