the thing that everyone should understand is that these are startups without needing to make an ICO. They are not protocols or coins they are just an Ethereum use case without the need of a token. So that's why the price tanked and all prices of all ICOs that don't need a blockchain or don't need their own token will tank. Just find out the good protocol and technical innovations and buy those ICOs.
Every year many beginners come to the cryptocurrency market who do not understand anything about it. Do not study projects, neither technical part, nor potential application in the real world. And just buy because you like the cover, and then cry that the money is lost. But the market feeds on hamsters, that's its fuel.
