He shook up the poker world with $19M swings against Dan 'Jungleman' Cates, but who is the crypto casino mogul taking on the game's elite?

Ossi Ketola, also known as 'Monarch,' made the headlines last week when he put out an open challenge to the world’s best high rollers. He landed a series of six games with Cates, and despite winning two of the first three, he lost the last three – and they were the big ones, with buy-ins of €5M, €5M and €6M. Jungleman won around $15 million in total and Ketola lost around $19 million over the course of these and other high-stakes heads-up games.

Ossi Ketola finds himself on the wrong end of another cooler. Ketola's streamed heads-up match versus Jungleman included the biggest pots ever seen on screen.

While Cates had a small piece of himself, Ketola has claimed he was playing 100% his own money. While there’s an element of ‘Trust me, bro’ on this, it’s almost definitely true. He’s extremely wealthy, and who’s going to stake him to play the world’s best heads-up players?

“I’ve become poker famous,” Ketola said in a random chat on Kick.com. But who he is, where did he come from and how much money does he actually have?
