To be honest, Investors should not really be asking such questions about coins/projects, if you actually believe it's the perfect time to buy Neo, we should take it to mean you have done your research about the project and come to the conclusion that buying neo is great atm, thus there is no need to ask for the opinion of others. The thing is, the coin might have been around in the market for a pretty long time, but can still be a bad choice, but it's all in your hands, just do your own research and make sure you choose coins that are long term projects and you believe in their network.
