Confirmation time
Confirmation time to me isnt the real big deal here to me it's selling it, cant sell them for paypal, cant sell them on debit...well you can just not "safely" i just dont like how unsafe selling btc is
Great currency for small-major transactions without having to file any of it majorly.
Confirmation greatly affect the time and trouble for me. Since I've pending for more than five days and it was very disturbing. Perhaps if the transaction can be with a fast time can be better. Because how else is the number one user comfort.
