KuCoin's going to be your best alternative if you're looking for a somewhat reputable exchange that doesn't require KYC upfront in order to trade; there's other exchanges out there that don't request KYC as well but most of 'em are much smaller and shadier IMO. I don't find Binance to be especially shady, but it's got the best volume for most alt pairs. I know some people that use HitBTC as well, but I'm pretty sure they do request KYC if that's something you're looking for.
