Afaik yobit is the only one now, bleutrade had faucet few years ago but not really sure whether it is still existing or not. Anyway why you look for faucet inside of an exchange while you can visit many faucet sites if you really want to earn from faucet.
I do even think that faucet inside an exchange like yobit gives you less amount compared to usual stand alone faucet. So what's the benefit of claiming faucet inside an exchange?
