I think that you should pay attention on such coin: Ethereum, Neo, ripple, OMG, ADA. I would still advise the EOC, but he is influenced by such phenomenon as pump, so wait and you can buy it.
For me Loyalcoin is one of the best then, Utrust, or Tky and Pundix these four altcoins are good to hold em in a long term dude. And those coins
that I mentioned is good to buy now due to its cheap better and timely to avail the chance then hold mate.
