Of course, it’s still the N.B.A., and the fraternity of Top Shot aficionados engages in plenty of antics and inside jokes.

In the locker room and on team plane rides, Mr. Ross and teammates Cole Anthony and Michael Carter-Williams answer questions from curious coaches and debate which vintage basketball play would make the best Top Shot.

“We’re making jokes, like, in-game,” Mr. Ross said. In a game against the Washington Wizards, for instance, Mr. Ross had an impressive dunk, and Mr. Carter-Williams told him as they ran back down the court that he hoped it would become a Top Shot.

In San Francisco, the Golden State Warriors guard Damion Lee — also a Dapper investor — is trying to start a new tradition: having players swap Moments instead of jerseys after games.

The king of Top Shot, though, is a Sacramento King: the rookie guard Tyrese Haliburton.

Bored one day in February, Mr. Haliburton checked Top Shot and saw the value of a Moment featuring him had grown by $600. He posted about it on Twitter and immediately saw another spike, piquing his interest.

“From there on, I was full go with Top Shot,” said Mr. Haliburton, who owns 163 Moments and has spent months exhorting other players to get involved.

During one postgame interview, he even urged Sacramento journalists to pool their money to buy a $10,000 highlight of his 6-foot-4 teammate Buddy Hield dunking over 7-foot Mitchell Robinson of the New York Knicks.

“There’s only 50 in existence, and you will never see Buddy do that again,” he said. They laughed at the advice; Mr. Haliburton, who makes $3.8 million this season, clearly did not know how little journalists earn, they said.

The next day, the Hield Moment surged to $50,000 in value.

Mr. Haliburton, who also invested in Dapper recently, has persuaded at least four other Kings to join Top Shot, including Harrison Barnes, who was “hooked.”

Mr. Barnes, the secretary-treasurer of the players association, is another veteran with a reputation for financial smarts. He owns 242 Top Shot Moments, the most of any player.

Mr. Haliburton thinks the Top Shot bets will pay off.

“I have a real belief that this is the future of our world,” he said. “I’m just going to keep collecting.”
