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?
Bitcoin transactions are Mainly Confirmed Within 20-60 Minutes But If Your Transaction is Taking More time then There May Be the Following Reasons:-
1) If You Pay Low Feeds For the Transaction then it Needs More time to Confirm Your Transaction.......
2) Or If the Bitcoin Network is Weak Then Your Transaction Becomes Slower.......
