any idea if those zeta coins will go back up? they keep getting lower and lower.
They were massively overpriced so I wouldn't expect the price to move a lot for the next little while. There isn't enough uses for the coin to justify the price it reached. Assuming services show up the price will of course increase but right now it's just people trying to trade to make a quick buck.
This is also true for most altcoins so I am not picking on ZET at all.
I think you're grossly overestimating use-value ... coins including Bitcoin do not get their valuation from people actually using the coins to make purchases. It's also that, but I would say it's behind 1) speculation (long or short term holding for speculation or belief in future technology adoption) ; 2) hedging against fiat inflation
for reason 2 zeta isn't better than btc but for 1) it is because it's quicker.
