Pump, dump, speculation, and so many lands lost !
A look at any asset class in the whole of history always shows you dont just have one option, metals (gold, silver, platinum), real estate (commercial, residential,) shares (so many), so it is only natural that cryptos will have many. Bitcoin is of course king at the moment, but the fact that litecoin is similar to it in many ways, may make those people who are looking for diversification from bitcoin more comfortable with it.
We are now leaving the phase of cryptos being just for those in the "know" and the masses are entering, LTC will appeal to them.
