Don't base your opinion around what some random people tell you over the internet! This is very risky to listen all of them, because their opinions could be easily made if they have invested in NEO, if they have they might tell you to buy it and other way around. Try to draw your own conclusions, but bearing in mind that NEO has risen exponetially last year tells you something at least.

NEO should be investment for long term and not used just to flip some money fast in my opinion.
