-1. I would never do a UR to UR transfer, but I know people who unfortunately do it.
I've done over 2 Million UR to UR to brokers this year, and no I wasn't AA'ed BH. AA happens for other reasons, never from that. UR shut downs only happened once, when they closed many Sapphire cards, never did it happen from INK to INK transfers, and I always felt it to be the safest method to sell.
