Last week, his older brother Logan, 27, revealed that Jake, 25, had lost huge amount of money after the cypto market took a huge hit.
The conversation came about on an episode of Impaulsive, when Logan used air quotes when referring to Jake's 'boxing career'.
Co-hosts George Janko and Mike Majlak then pointed out his success in the sport along with the big pay-days for each fight.
"It's going pretty well, he's won every fight he's done," says George, before Mike says: "He made like $40 million last year."
However, Logan corrected the pair and said: "It doesn't matter, he put it all in crypto... he's poor."
Well, Rob Moore asked Jake on his podcast if Logan had received full payment for his Mayweather bout last year, and Jake was pretty straightforward in his answer.
Jake replied: "Nah. Floyd Mayweather is broke. I've been saying it all the time.
"I think he probably spent it on the girls he pays to be around him."
With all these allegations, it's hard to truly know who is truly broke and who isn't – let's be honest though, I'm sure they're both still very well off.
What we do know is that it's been more than one year since Logan fought Floyd in the multimillion dollar fight, for which Mayweather was expected to earn £52 million and Logan was to earn £15 million.
However, as captioned by Logan in an anniversary post on social media, he wrote: "One year ago today, I fought Moyd Fayweather.
"He's hard to hit, but even harder to collect money from. Who should I fight next?"
Mayweather hit back at the YouTuber at the press conference of his next exhibition fight, in which he will take on Japanese mixed martial artist Mikuru Asakura.
The 45-year-old said: "This is the guy who said he didn't get paid, which we know is truly false, which is why I don't entertain the bull**** a lot of the time.
"We know he got paid and if he didn't get paid he wouldn't be trying to get another payday. It is so crazy that Logan Paul wants to do an exhibition again but it is the same guy that said he didn't get paid. It is what it is."
Mayweather also told The Pivot Podcast: "This comes with the territory.
"To them, that's real money, and I like the YouTubers. The money on the back end though, from pay-per-view, that takes a while.
"Nothing comes right away. I'm still collecting checks from fights seven or eight years ago.
"They just hate when the table is turned. Be happy with the biggest payday you ever got in your life."Featured Image Credit: Instagram/@jakepaul/Shutterstock
