What are some of the best ways to convert fiat to Bitcoin, without having to provide identification to a third party?
Ideally something that would work in high volumes, electronically and at low cost of conversion.
Some methods:
*Cash in person
You will agree with me that this method is not convenient, and you will also agree with me that by this method, you have automatically KYCed yourself, because you've meet the person face to face, he knows you and in the process of exchanging cash and bitcoin, he or she will end up getting one or two information about you.
*Money orders
I don't know about this method so I won't comment on it.
*BTC ATMs without KYC or security cameras (are there any?)
*Bisq (various methods)
You will hardly find any ATMs or( fully put), bitcoin ATMs any where around the world without security cameras, even when there are no CCTV cameras around, the machines come with their own built in cameras with some time is hard to notice, but it's there.
What else?
It all depends on the country one is living in, like in my country, it's currently very hard to find a means to convert fiat to crypto with out any form of kyc, though some kyc, like level 1 kyc on Remitano only required a phone number verification, with this, you can buy bitcoin with our local currency but at a very limited daily capacity or quantity.
