Thats one more proof that we urgently need to increase the blockzise.
Block are already full and ths kind of dealys are getting to be more common. This is bad because it causes a lot of issues between buyers and sellers.
It can even mine the trust in bitcoin on businesses as shops who are already accepting bitcon.
Yep, I've encountered this delays occasionally which sometimes pisses me of cos i do not like waiting for hours to get it credited.
