Very good question. First of all I would expect around 80% of current ICOs to fail - high number but we have to be realistic. A lot of these projects are very ambitious and directly competing with existing products that have been around for years. For example bitJob - if you Google 'student employment website' you will see hundreds of pages. bitJob will have to compete with all of those and might potentially fail.
Does that mean it will be a bad investments now? Not at all - crypto market is growing quickly and bitJob tokens will probably increase in value when the project is being developed and there are often early signs that the project is failing when it is indeed failing like less communication from team, less updates, no significant development. There will also be time to get out of the investment before the price competely goes down. Keep in mind I'm taking about long term investment here.
I actually think most of the ICO investors are looking to make short terms gains aka dump coins on exchanges and ICOs are great for that :) This is what I mostly concentrate in my reviews.
There are few ICO projects that I think do have potential to survive and become the giants in the respective industries. From the recent ones OMG and TenX for example. There are few future ones too. I think Kin could get blockchain mainstream. Then there are specialised projects that could dominate specific sector: Cindicator could become the go to app for investors, Red Pulse for market research, Modum for logistics, Viberate for live music.
Blockchain is better than traditional approach so I think many early blockchain products will get a headstart and catapult to compete with the traditional giants.
