Binance is one of the better exchanges out there that still don't require KYC.
If you are looking for an instant exchanger however there's really a severe lack of good services available right now in this climate where regulators are cracking down heavily. You could potentially look at both Changelly and Changenow as options, but honestly, they're quite shady in their own rights.
But if you are going with small amounts, it shouldn't be that much of an issue anyhow.
do you really know what he wants? binance does not provide dai and sai markets
someone know the best website to convert usd tether to makerdao dai or sai stablecoins? with low or lowest fee to pay for convert usdt tether to dai , and that not need kyc verification
for dai maybe you can exchange it there (kucoin) the exchange is still reliable and I have never experienced a problem, but for sai I see the list of exchanges at coinmarketcap never use this exchanges, so sorry can't suggest anything
