That would be a valid statement if there would be any economic model which could help us to assess the fundamental value of altcoin. What the problem is with altcoins at page 2 - 3 on coinmarketcap is low liquidity so It can get pretty nasty if you want to get out. Low liquidity and guessing work about which one will make 50% tomorrow it same like a lotto you hope for big win.

On another side up until the dumb money flows in crypto the top 50 market coins will grow no matter of underlying earning potential. Nobody relay knows what is earning potential of any crypto project i.e. ICO.
