What merchant uses a static address for all customers? Horribly insecure and prone to problems. Anyone that foolish should just use a service like bitpay and have it done right by someone competent.
Just about every in person retail merchant I've ever seen.
Quote from such a merchant "I like taking payments directly versus using a third-party processor like BitPay or Coinbase because it is more in the spirit of bitcoin. Why fill out an application and give up all your personal info when you don't have to? Bitcoin is your money." Is bitcoin our money or is it the miners money?
What makes it "horribly insecure" other than having the transactions visible?
