Hoped that you stayed strong along the ride and had made good decision with your fat stack of bitcoins, diversifying is always a old school method to keep your funds stable with market movements, going into big chips like Ethereum, Monero, Dash certainly wouldn't got wrong over the years, supposing your style of holding had paid your efforts, it's good to invest more, learning more from other altcoins/projects to make good market decisions on trading, holding is fun and exciting for me.
