See bitcoin transactions depends upon the speed of youe internet
But usually it takes upto 1 hour
not really, its depend on the network traffic and if the network can handle many of transactions then i think for completing the transacting its less than 1 hour and i have many time to receive the bitcoin amount in less than 30 minutes.
i think it also depend on transaction fee, if you pay more then the transaction will be faster than you if you pay a minimum fee. but it also a fact that the transaction also depend on network traffic.
