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?
You said "0/3" confirmations which make me think you are using a third party service and not viewing the transaction in a blockchain explorer. If It's the case then there might be some problems with the service you are using , If you are not using any , then your friend probably didn't pay the recommended fees (post the TXID so we could help you more).
