I've done the same, most recently with a certain Metal 3D Printing start-up. Bought late in the initial rise in its first couple of days, and it dropped shortly after. When it finally went above my buy-in I sold out at ~$1.2? 2-3 months later it sky-rocketed to ~$5.5... Felt so silly having sold out...
