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.
Indeed, it is considered to be one of the most successful projects in world monetary history. However, a long time later, until now, it has not had any outstanding development yet.
