I had a friend send me 100$ btc and it's been over an hour and it's still 0/3 confirmation. I normally get them instantly or 30 minutes tops. Is their an issue?
It could be that the fee was smaller than the network average and thus its being pushed back, or there could be a block taking a REALLY long time to go through. It's happened to me on a few occasions and it wouldn't surprise me if it was happening again.
