I've been watching bitcoin since $10 or so, and always thought that I should buy some. At $30, I thought it was too late, but when it went to $250, I resolved to buy more if it crashed. It did, and I bought five at $80, just to get my toes wet. I planned on buying more if it ever dropped that low again, but of course, it never did, or hasn't yet... I just sold one this morning to cover my initial investment. The 4 I have left are all profit, and I'm gonna let them ride.
