This is my incoming transaction:
https://blockchain.info/tx/397fc251b556d7d89a0a6ecca2c349a7ca1b44c3b0eff5042c6f686b8dcfaaecWas sent more than 1 hour ago and still Unconfirmed.
Why?
It said "Estimated Confirmation Time:
4 hours", now it's 5 minutes, but it changes all the time.
Why transaction behaves in this way?
