5x$500 is almost enough for an extra Bitcoin.
Just a thought:)
i know but looking for something promising which can grow 10 fold and still be under 1Billion market cap.
If you want find altcoin can growth x10 in long time, I suggest buying MobileGo, this is token use platform Waves and Ethereum for development, and the project raised high than $50 million dollar after crowdsale. I think in 6 months - one year, the price of MGO growth x10 x20 is possible, because the price in current still very cheap.
