I use Bitfloor because it's the easiest exchange for me to move dollars into, so I buy bitcoins there and immediately withdraw them to cold storage.
I wonder why a CapitalOne360 P2P deposit (formerly ING P2P) would take 3-4 business days to be credited to my bitfloor account (according to bitfloor instructions), when the transfer is virtually instantly? What is bitfloor doing with my funds during that time?
