To be honest, these limits are quite massive for a non-KYC exchange. I've known in other exchanges that haven't forced verification yet, that they're likely giving 1-2 BTC withdrawal limits per day.

I haven't used these two exchanges yet and thanks for the idea but it won't be surprising anymore if soon they're going to change this policy of theirs for their non-verified accounts.

And with mandala, seems new to me but it's interesting that there's still handful exchanges that don't require kyc.
