Finally... A suggestion for another criteria. Can you give us a list of these AI based coins please? That could be the next niche that's gonna get a lot of hype. Not saying 'AI on the blockchain' is really gonna be the next big thing of some sort but the devs and the shills will surely make it look that way and hype the masses into giving them a lot of their hard earned money. 
True. The problem when following such artificial hypes is that you are never investing because of the product being advertised and its purpose, but solely because there is a hype going on. Therefore, it's not possible to measure how worthful AI projects in particular are to be invested. It can be one or another, and you have to be lucky to pick the one rich speculators are going to choose as well.Main AI projects, which really make the difference nowadays, aren't raising funds through crypto tokens. But for those who want potential profit from the currently trend, they might try that, just like people who invested in Metaverses' projects last year.
