Investors have been on vacation. VIA isn't even only two months old, and whales don't like risky new things with low volume.
Once VIA demonstrates its VIAbility over time and the hype about treechains gets around, we'll see more price action.
Until then, enjoy the cheap coins.
If you use the filter to remove premined/nonminable shitcoins, VIA is #12.
