The popular tourist destination Isla Mujeres in Mexico (also known as Woman Island in Spanish) has a content creator who initiated an experiment called '21 Days Only Using Bitcoin.' Faced with limited income and the pressure of shops not accepting cryptocurrency, it reflects the challenges of integrating Bitcoin into everyday scenarios. (Background: Bitcoin's market share has dropped below 60%, hitting a six-month low. Is a new wave of 'altcoin season' coming?) (Additional context: Harvard University's investment portfolio includes $117 million in BlackRock Bitcoin ETF.) A young girl named Isabella runs a YouTube channel themed around 'Bitcoin' called BTC Isla. This week, she started an experiment on Isla Mujeres, Mexico, to 'only use Bitcoin for 21 days.' The rules are simple: no access to bank accounts, cash, or mobile payments, only earning and spending Bitcoin (BTC). She started with a wallet balance of zero and must find work every day to earn BTC for living expenses. She documents her daily process in videos on YouTube, and she is currently on day six. Note: According to her video, Isabella has lived on the island for over a year and has been filming content about Bitcoin and blockchain knowledge for the past ten months. Day One: Starting as a Bar Apprentice According to the video, Isabella chose to apply for a temporary bartender position at a familiar tavern. The owner offered a daily salary of 270 pesos (about $14) and agreed to pay in Bitcoin. She washed glasses and made smoothies in a hot kitchen, placing a transparent bottle labeled 'Bitcoin Tips' as a tip jar, attempting to encourage customers to tip via the Lightning Network. After eight hours of work, she finally received about 11,000 satoshis, equivalent to about $14, which became the first seed for her living expenses over the next three weeks. BTC was earned, but the shop wouldn't accept it. After work, Isabella immediately went to a large chain supermarket to buy daily necessities. In the video, she estimates item by item: a barrel of drinking water for 30 pesos, bananas at 29 pesos per kilogram, and local fresh fish at 192 pesos, totaling exactly what she earned today. However, the cashier's response of 'We only accept pesos, not Bitcoin' left her empty-handed. She helplessly explained, 'It's not that I can't afford it, it's that they won't accept it.' After the shopping failure, Isabella returned to her temporary residence and proposed a strategy to the camera: 'Next, I will visit corner grocery stores and family-style restaurants to convince them to download wallets and accept the first Bitcoin.' Additionally, she showcased an empty house under renovation, announcing the opening of a 'Bitcoin Cafe' on August 21, aiming to combine the aroma of coffee with crypto education, and writing a slogan on the exterior: 'Come for coffee, stay to join the revolution.' In her subsequent videos, she revealed that she had successfully convinced over 20 shops to adopt cryptocurrency payments, but 'some shops haven't traded in a while and are out of practice.' This challenge thus became an 'opportunity to reawaken' them. She stated she would continue to set an example by using Bitcoin for consumption and ongoing education to make Bitcoin payments a norm for businesses rather than a fleeting novelty. The Bitcoin test is still ongoing. Currently, Isabella has continuously updated to day six, and I believe she will keep updating until the opening of her Bitcoin cafe. Many content creators discuss Bitcoin online, but few, like her, are actively promoting education on a small island.
