Lol. If you have Bitcoin, you've already invested in one of the fastest growing stores of value out there. I and many, many other members would suggest you HOLD.

But that aside, if you're determined to invest bitcoin, I suggest lending it out on a trusted platform (Bitbond, Poloniex, BTCLendingClub) and reap the interest. Other investment opportunities include buying into ETH or XRP, both of which have seen +4000% gains this year. And if you want to invest in some interesting token sales, in the hope of much larger potential rewards, I'd go with Nucleus.Vision, Leverj and Monero (if you can get your hands on it)
