in the present day bitcoin transaction is slow.but if u are comparing that with credit card transaction it is too slow ..it may take some while to cope up with the same transaction speed with that of bitcoin .well i can assure that in the near future people will transact through bitcoins and it will be same as the bitcoin transaction and convinient too ..kudoos 
to me the transaction of bitcoin is really too fast but in fact the verification process is really so, i think that issue must be solve on priority basis other wise it is really effecting the image of bitcoin as if you are going to trade something in bitcoin then you have to waif to hours for verification of transaction and that become a big problem then.
