Look there will always be dips and panic which I think are opportunities but you have to ask yourself what it is about neo that you like? For mine there is a lot going on and the ecosystem is starting to mature.
I always hold neo.It is getting better and better from its community,technology and so on.Although the price has dropped a lot now.it is developing in every aspect.
I have been hodling onto NEO since the Antshares days, and over the past few months I've kept adding a few more NEO when there has been a dip in price. I think NEO is the one to hodl for the long term, it's in a bit of a dip at the moment but so are all the alts - the future looks bright for NEO.
