A friend sent me Bitcoin to my blockchain wallet. It shows the amount as part of my balance. However, it says there are 108 confirmations and the number of confirmations keeps going up. Why is this happening? Can I spend this Bitcoin while confirmations are continuing?
The number of confirmations indicates under how many blocks your transaction is buried. The more the confirmations, the more your transaction is secure from double-spending attacks. So the confirmations will continue growing forever - this is normal behavior.
