Suppose someone sent me bitcoins and in my wallet it started showing 'awaiting confirmations'.Can I be sure then that I will get the coins properly?
Actually I want to lease my rig.I want to set the mining for a renter as soon as possible.
Can something go wrong during confirmations?How about after 1 confirmation,can I be sure than?
These days you should wait for at least 1 confirmation. There was a bug that affected unconfirmed transactions so better to be safe than sorry.
