If I had any BTC (lost them all recently
) I would invest in the smaller Crytocurrencies like NovaCoin or LiteCoin (NVC seems like a better choice). Of course you could always see what new ones are taking off right away and just increase your money by ten folds since they'll be worthless but they double easily if they take off. Spent 25$ on ChinaCoin when it first came out then made about 80$ back within the week.
https://twitter.com/fontase I've followed this guy a couple of times but pretty much did the exact opposite of what he wanted which seemed pretty lucrative (Only if he announced the coin). Followed this twitter like a hawk a few months ago.
Also if you have your own business that isn't website based, start to take Bitcoin as a method of payment.
