I am legit surprised that Litecoin isn't #2, now I know I don't clarify this much but Bitcoin is gold, Litecoin is silver. If you only have so much to invest, do you buy gold or silver not in a physical commodity but a digital asset that has a long-term upward trend. It's a buy and long term hold. Crypto-Currencies are a $1,000,000,000,000+ market.
