It's not an artificial pump, it was actually (for the most part) someone buying up all the supply for 2 days (it's a hyposesis but look at the chart, it can't be otherwise) but he didn't do it to pump it, he just knew how valuable GAS is. What's more important is that people didn't understand it's purpose until 24 hours or so ago. Then everyone rushed to jump in and this happened.

And it's not more expensive than NEO, marketcap-wise it's about 1/15th it's value because of the decreased supply (it's supply will grow but it will take some years before it's even close to NEO's).

Also, noone can vote on the value of a coin. It's value comes from the demand people create.
