As the year 2018 has been speculates to be the year of altcoins will it be better to invest into bitcoin or altcoins ? Which one will give more return in both short term as well as long term ? I am bit puzzled whether to go for well established bitcoin , Litecoin, ethreum or Ripple, Dodge coin, Dash.
Obviously it's altcoins that'll give you more return. Bitcoin is just a currency that you use as your medium to trade with various altcoins. Trading altcoins has its own limitations so beware of it. To add to your list, I'd suggest you, XLM, XEM, POWR, XVG. These coins have been pumped quite frequently so there's a good for it to get pumped again.
