I am trying to make my first Bitcoin transaction, so far unsuccessfully.
I have set up an account with blockchain
I have my BTC address and the vendor's BTC address.
But I need to know how to pay for merchandise:
I thought blockchain could use a credit card number, but so far it is refusing to proceed with the transaction.
Do I have to buy bitcoins from an external site, then put them into my wallet, then buy the merchandise?
I have also read in a tutorial that I must first buy a small amount of bitcoin to activate the wallet. Why not just buy the entire amount of my purchase in Bitcoins then transfer those over to the vendor when I make my purchase?
Assistance would be appreciated.
