Is there any chance that the confirmation process will pick up in speed here in the future? I think some people are not accepting them because the time it takes to confirm a transaction. I know I do not want to be standing in a store for 20 minutes or longer to wait for a candy bar.
There is not realy necessary to stand and wait for number of confirmations. When transaction is broadcast, then it`s visible as incomming. This is within a second.
It depends how owner of the shop will implement confirmation system to trust that transaction.
