Depends what you expected those initial coins to do. Did you get them as a speculative investment with a chance of "interest" of x%/year? Then a 100% increase is pretty damn good as far as investments go, you shouldn't feel too bad about selling now. You'll have regret if it continues to grow to the moon, so maybe sell half or 3/4. But also calculate the potential unrealized earnings if it went to the moon -- i.e. if your little pile was only worth $100, now $200, even if it doubles twice more the difference is just $600.
