Instead of selling normal tickets to the party — which featured a performance by the Russian punk-protest group Pussy Riot — Friends With Benefits required attendees to scan their crypto wallets at the door. If you owned at least five $FWB — the group’s membership tokens, which cost about $140 apiece as of party time — you got in. Bringing a plus-one required having 75 $FWB, or about $10,000. (There was a way to skip the line altogether: win an auction for the party’s official NFT, although that ended up selling for more than $50,000, making it a poor choice for the budget-conscious raver.)
