Why are Ethereum and other Crypto's falling along with their mother bitcoin ?

ICOs created a mess of Crypto's. We still don't know what EOS is and the people behind it keep shouting that it is priceless and worthless but still people flooded their precious Ethereum to be part of EOS like ICO's only in a greed to win more and more. Ethereum and all other crypto's would have never seen such a bloodbath no matter how deep and severe the Segwit issue had caused to BTC but it is only because of ICO's that we are seeing Ethereum bleeding to its brain.
