The Bitcoin 2021 conference may have come and gone, but it’s having a lingering impact as attendees are beginning to test ꧑positive for COVID-19.

The Bitcoin convention was held last weekend in Miami, with some 12,000 attendees. ಞAs one of the first in-person events to happen since the pandemic’s outbreak, Bitcoin 2021 had no mask mandates or proof-of-vaccination requirements. People came from all over the world, mingling for three days.

In the aftermath of the event, people started testing positive, leading some to label the conference a “ꦡsuper spreader event.”

Some Twitter 🍌users are already condemning those who attended without being vaccinated, saying it showed reckless disregard for the 🧔health of others.

I can’t believe people attended a massive in person conference without being❀ vaccinated. It’s not just risky for themselves but it is reckless in regards to others

While it’s not clear how many have been infect🎀ed, some users indicated entire groups of people they were hanging out with have all tested positive.
