Yes they have Petron you can read it in the whitepaper.

This coin has sufferd allot and I see a great opportunity to make allot of money. for the people who dont agree look at ETH CASH and ETH Gold they had no websites or even a whitepaper yet after the site was upgraded (Still not good in my opinion) they launched you can look it back if the DEV team of NEO Gold upgrades the site they will increase in value easily 0.5$. They are active on socialmedia even tho they are little now i think that will change soon. I had a small talk wit the DEV team they are working on it i didnt get any info only that they are working on the project.

So if you dont buy NEOG fine) someone else will and if you wanna sell them reply i will buy them
