An annual bitcoin conference is expected to draw around half as many attendees as last year, indicating how a drop in cryptocurrency values and growing regulatory actions are rippling throughout the industry. According to Brandon Green, chief of staff at BTC Media, the conference, dubbed Bitcoin Miami by attendees due to its location, is anticipating more than 12,000 in-person attendance when it opens on Thursday, down from 26,000 last year. The collapse of cryptocurrencies and crypto firms last year, most notably FTX, is also projected to result in a more subdued environment.
