If you have been watching the crypto markets lately it is obvious that these two coins are sticking out with the only two that are on an uptrend and staying strong. The reasons I think this will continue
Litecoin will have 4x the currency of bitcoin thus meaning in theory will be 1/4 the price, litecoin is well below 1/4 the price mark leading me to believe it is incredibly undervalued.
Litecoin and Dash are much more efficient with their technology and a lot faster moving with their programming giving it a leg up on the slow moving bitcoin community
Dash has a very unique ability to be completely anonymous and with the growing concerns of regulation in the crypto market, giving it a leg up with the other cryptos in the market right now.
