I recently came across a brick and mortar Bitcoin OTC brokerage in the old town of Montréal in Quebec. It was housed in a tiny space in a touristy area, advertising rates for various cryptocurrencies and fiat currencies. I had previously mainly encountered such places in Asia, so I was curious to try it out.
The whole process took about five minutes. I walked in, stated my interest in selling 500 CAD worth of Bitcoin. I was told that Lightning was generally an option, but not that day.
I was shown a BTCPay Server checkout page. I scanned it with Bluewallet, selected my onchain fee and made the payment.
I was then asked for my phone number, name and country of residence, but not any form of ID. I was given the cash without waiting for confirmation and headed out.
Cash received: 500 CAD
Sats paid: 361323 SAT
Onchain fee: 438 SAT
Rate given: 138,380 CAD/BTC
Market rate: 144,653.00 CAD/BTC
That's about a 2.9% markup over Shakepay, or a 3.3% markup over Bull Bitcoin, so I likely won't do this too regularly, but given my difficulty of finding somebody locally who is willing to buy sats peer-to-peer, like I would in Vancouver or Europe, the OTC brokerage is my only option for getting cash.
