Then she started taking bitcoin, and the first thing three different people told her was to use a payment processor. A payment processor is a company that takes the bitcoin from your customer, holds it, and sends you money later. It is convenient. It also means the coins sit in somebody else's account with your name printed on a screen.
Start with the key itself. When you hold bitcoin yourself, you hold a private key, which is a long secret number that authorises a payment. Whoever holds that key controls the coins. That is the whole system. There is no manager to call, and there is also nobody who can freeze you.
Most of the worry in this space goes to confiscation, meaning a government taking coins by force. For a small shop I think that is the smaller risk. The bigger one arrives without a headline. It is the account closed because your business category got reclassified. It is the processor pausing withdrawals for a compliance review during your busiest week. Nobody took anything from you. You just cannot reach it.
The strongest case against me is a fair one. Running your own keys means you can lose everything to a fire, a bad backup, or your own fat fingers, and a processor gives you accounting, refunds and a phone number to shout down. For a lot of shops that trade is worth making. Plenty of businesses have used one for years and had no trouble at all.
What would change my mind is a number. If businesses holding their own keys lose more money to their own errors, year after year, than businesses on processors lose to closures, freezes and review pauses, then I am wrong and the convenience wins. Somebody could count that. I have not seen anyone try.
Bitcoin is the only money where holding it yourself is a normal option rather than a special arrangement you have to negotiate. The coffee shop owner already worked this out with cash. She keeps the key to her own safe. The open question is whether she gets to keep that habit when the money changes shape.
