I just thought about this today. Every time you are transacting with bitcoin, you will be told that you have to wait for bitcoin confirmation. This is common with bitcoin gambling sites. What I know is that bitcoin transactions are irreversible. Then why is it that you have to wait for the confirmation before initiating anything?
I want to say only one thing when we make every day transfers, when we go to the bank does the bank says wait a bit until the transaction get listed on the system?
Also when we make international transaction, shouldn't we wait for few days until it gets "confirmed" that's with bitcoin transaction too.
