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?
Its Not Possible to Predict that How Much a Transaction needs time to be confirmed, There May Be Two Reasons Behind this:-
1) If the Sender Pay Low Fees then the Transaction Needs More Time To Confirm Sometimes it takes 24-48 Hours to Confirmed.....
2) Or If the Bitcoin Network is Slow then its Not Possible that the Transaction Will Confirmed Faster.......
