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.......
Actually the bitcoin transactions can be faster if you don't mind to additional the transactions fees. But sometimes the confirmation of transactions is long time enough and we should wait it patiently.
