You must be aware of the whole Bitcoin scaling issue and high transaction fees. I feel that the current price of Bitcoin is quite speculative, mainly because of the upcoming forks. Don't get me wrong here, I love Bitcoin, but recently it has lost its true intention of being an electronic peer-to-peer cash. I feel that there are many other cryptocurrencies like Bitcoin Cash, Litecoin, and DASH that are much closer to the ideal electronic P2P cash.
I would recommend cashing out the initial investment and then just playing around with the remaining bitcoin. Save some for future blockchain splits, sell some for altcoins, etc.
