Im not sure if they are dead already but I just haven't seen a good IEO which i liked.
Most of the IEO's are also releasing on Binance which I dont really use much because they have such High Fee's, I should maybe buy some Binance Tokens to reduce the Fee's.

But they where pretty expensive in the past so I didnt yet, I am hoping there will be a good IEO in the future because I deem them safer then a ICO at the moment.
