In binance there is not so important that we have to do compulsory KYC.Binqnce is a big exchange and has a huge volume in Bitcoin and other coins then any other exchange.
If we are trading in binance less than 2 BTC per day then no need of KYC required if we are doing trading more than 2 BTC then it is compulsory to do KYC then only we can trade on the Binance.
KYC is important for heavy transaction or bulk transaction so there should be needed of KYC .you can give KYC in binance because binance is a big exchange and it is running from several years.
