Okay here is a good sign. Especially when you have an entire smart economy that is running on gas coins. There has been some news articles, stating that the Chinese yuan will be replaced by neo. Sense the demand for this coin is determined by the transaction level. You can conclude that as neo coin becomes more accepted into the economy or smart economy. The price of gas will eventually go up, as people buy things with neo.
In the short run. It will probably go down a little more before it goes back up again. So in my opinion you should buy in at: 0.00486933 not the current market value price as of 11:57 AM EST. on the date of: 2/4/2018.
Obviously it is better to buy the actual neo coin if you can afford it. Because it creates some of the gas you need every year, and that is compounding. But sense the price of neo coin is 2x of what the price of the gas coin is. You can decide based upon your budget, what you want to invest in it long term. I have some in my hoddle wallet that I don't trade with, for that very reason. In my opinion, both are good investments.
In my opinion you should buy in at: 0.00486933
