Nebula AI is a dead project in a very competitive space. Move on as you can make more money in other cryptos that are moving up. Opportunity cost to hold nebulas AI costs money.
It is not dead, a lot of great events are ahead, but yes, they looks very weak on the market of hype. Great example is a comparison of quarkchain and pchain, where technicaly pchain is definitely much stronger than quarkchain, but PAI is trading now at x3 of ico price and QKC is already around x16... hype, hype, hype... those who can create it around itself are on top 100 currencies of coinmarketcap, all others stuck in depth.
