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. I really appreciated the bitcoin transaction i did because its so fast specially when cashing it out through my wallet. The transaction only takes less than a minute if your net connection is stable and fast. I do last transaction loading my mobile # its so fast to send and can be used immediately. I am also planning to do trading altcoins for next month because i heard trading is really nice to do with fast bitcoin transaction as well and will gain good profit.
