In my opinion, Neo has no value whatsoever after china banned crypto. Nearly no product using their chain and chain becoming deserted every day.
It won't drop to 0 but other chains will outperform NEO in 2019.
Neo in some time did not experience significant price movements, only in the range of USD 11 to USD 13. This has been seen for the past month. It will probably remain like this if there is no more attraction offered to investors.
But I am optimistic that Neo will still experience an increase which is the effect of bitcoin, but not too high. According to my prediction if the price of Neo until the end of the year is at most USD 20.
