Binance dont need KYC and enable trading between altcoins and withdrawing up to 2 bitcoin per day. More than 2 bitcoin require KYC.
That's right, unless they're not reaching the limits they can trade without submitting KYC. Then, if your really want to trade without it, you can trade at decentralized exchange such as DEX, Forkdelta, Coinexchange, Yobit, and IDEX.
