Bitcoin transactions are normal but the time taken for confirmation message of that transaction is more. It has to be solved otherwise buying goods in shops using bitcoins would remain only as a dream.
I think it currently do not have any issue for the shops as some of the companies accept bitcoin with zero confirmation but if a problem of zero confirmation started then people will want for 1 confirmation. The developers have to work for the purpose that they device a tool for bitcoin technology that first confirmation is completed as soon as possible without any delay.
