I think NEO founders are going to be connected to some of the first ICOs, so I don't think they want the price driven down. Who knows when shit gets more popular. Sure some scammers in the west will hop on it since they can avoid the SEC in China.
Look at the marketcaps. One is around $90 million. One is at $2 billion. In order for you to get a 5 times return, GAS only has to jump to $450 million. That ain't shit for it to be part of the NEO project. NEO has to jump to $10 billion.
Also, if I'm a whale holding NEO and generating 10-20 GAS per day, I'd want the price of GAS to go up high as possible. Why get hundreds of 'free money' per day when I can get thousands?
Another thing to think about. NEO isn't divisible. So if it goes to $1000, 'joe average' needs to pay $1000 to get in the game. Meanwhile, gas is divisible 8 decimal places just like bitcoin. If it were to hit $1000, you can still get in the game with $50 just like with bitcoin.
Many NEO holders don't understand that it is in their best interest for GAS to go up. On reddit, a lot of folks still on GAS vs NEO like they are not part of the same fucking project. It's insane. NEO is like a mining rig for GAS, and you want GAS prices to stay low?
I'd go 50/50 if I were hopping in right now, but do some more research and come to your own conclusions.
