I think the cheap crypto coin is for the short term investor because it might not last long in the exchange market. It is better if a long term investment is a reputable coin like Bitcoin or Eth because they have the staying power compared to other coins that are flash in the pan only.For a long term investor ,i can say investing in a cheap cryptocurrency now might be of benefit in the future.Bitcoin is not actually rising like before again and this might give opportunity to other cheap coins
