I would diversify into other altcoins, then sell some BTC (if you live in/near a city maybe you could try selling them for cash, bring a nice big sign saying "selling BTC for cash", you might even be able to get 10-30% premium over the exchanges. You could also sell some BTC on localbitcoins, i've used it quite a bit and is legit (via bank transfer). I would also say to hold some BTC in cold storage for the long term.
