Bitcoin has been troubled in the last couple of years especially at exchanges where photo id is now being enforced however the so called AI behind it cannot accept ID. This ould be debated but i'm not American and american exchanges won't accept my ID. If I was American it would. But my point is that identification destroys anonymity within transactions and thats a big mistake in blockchain management. At the end of the blockchain is the banks thats the end point of anonymity so this photo id crap should be abolished.
