I initiated a withdrawal yesterday on Blockfi for a larger amount of Bitcoin. I will say that the withdrawal was larger than $5k. The first time I withdrew money I was asked to identify myself for a large withdrawal. This time that step was skipped. 

I believe the reason for that was due to withdrawing Bitcoin into an address which was added into my safe withdrawal address list. It may also be due to being a receive address for a prior deposit. Has anyone else had a withdrawal to see what BlockFi actually does as a procedure for larger withdrawal amounts?
