Visited the electronics district with @k1elsalvador to show merchants alternative ways to acquire bitcoin. They were instantly convinced. Will work with them to get familiar with @blinkbtc and accept payments, as bitcoin shoppers may arrive anytime.
The army of @k1elsalvador Bitcoin ATM machines arrived to our Roatán Bitcoin Center. Configured to lempiras they will serve the community across the Bitcoin Pirate island. Thank you K1 team for bringing them with you.
