But it depends on how it evolves. Bitcoin or any other crypto is not something static. In the future, when 1 Bitcoin is worth 1 million USD..and the fees for using it are close to zero..people will use it. The catch is only that for it to reach 1 million..people must use it :) But as it grows and develops, fees become smaller. Or Bitcoin could become digital gold. Absolutely. That could happen to.
Take Ethereum for instance. It has some utility all ready. You can use it to buy and invest in ICO's for instance. So it's always clever to hold ETH. Me personally I always make sure I have a reasonable amount of ETH..sometimes I spend ETH on ICO's or other currencies..but when I profit from those I put it back into ETH. And thats how a currency is alive, and not stagnant. Bitcoin however is stagnant at this point..but even if its bitcoin cash or core + lightning that brings bitcoin further, it must evolve to stay alive. It must be alive. Money needs to flow in and out of it. And I think it will. Even as a stable "gold".
