I sent bitcoin today but after more than 1.5 hours of waiting, I could only get 9 confirmations. Still waiting! Haaaaaaay.....
I don't think that any crypto exchange or site that uses bitcoin these days are using high numbers of confirmations, at least not these days, with how long and how much fees you have to pay in order to get transactions sent as fast as possible with a decent confirmation it would take several hours for it to do so, i think that most sites have started going for 3 confirmations since the network has gotten a lot of traffic.
