I like the cryptocurrency due to the privacy, i do not like to send my IDs to anyone even if it is popular and trusted websites, requesting KYC to participate in IEO is against privacy why i have to send my ID to participate in IEO!!
Most of exchanges launched their IEO platform required KYC.
Is there any exchanges run IEO and do not required KYC.
Depend where IEO coin listing, if you want to invest with IEO listing on binance exchange you have pass KYC before make investment because you have limited withdrawal when you cash out your asset in binance, for IEO coin listed with Bittrex you will never can make withdrawal if you not pass KYC because you mush submit KYC for withdrawal in bittrex and limited withdrawal in Bittrex is zero if not pas KYC.
It is true, in the crypto currency privacy is number one, but KYC is also very important to do in exchange because it helps that someone can be traced if they have problems like money laundering, even terrorism, but if the data is hit by a hacker attack it is a very terrible thing , if you want to buy IEO maybe you can use an exchange other than Binance, Bittrex or Kucoin
