Crypto is growing up: Goodbye yacht parties and NFTs, hello regulation and practical tech

• The three-day Messari Mainnet conference in New York was less expensive and less fun than it was a year ago.
• Gone were the Reddit bros and yacht parties, and in their place came suits and talk of regulation. 
• Insider's Phil Rosen caught up with dozens of attendees and executives at the conference.

Crypto isn't dead, it's just growing up.  

That's the sense I got after spending three days rubbing shoulders with crypto founders, blockchain pros, politicians and executives at Messari Mainnet in New York City. 

In contrast to previous years when the halls were full of tech bros and Reddit enthusiasts, most of the 3,000 attendees were buttoned-up professionals representing companies or brands.
