  • Sam Bankman-Fried catapulted into a crypto billionaire. Now, his empire is in ruins, and he's been sentenced to prison.

  • On Thursday, he was sentenced to 25 years in prison after being convicted in November on seven criminal counts.

  • Here's the story of his rise and fall from grace.

A few years ago, Sam Bankman-Fried was a 30-year-old with a mop of brown hair and enough clout to go by his initials, SBF. He had a cryptocurrency exchange called FTX, a trading firm called Alameda Research, and $15.6 billion to his name, according to estimates from Bloomberg.

He had catapulted into one of the biggest names in crypto in the span of a few years and was setting his sights on mainstream finance.

Now, he's been sentenced to prison.

A federal judge on Thursday sentenced the disgraced FTX founder to 25 years in prison, following his conviction in November on seven counts of fraud and conspiracy.

Here's how SBF went from crypto's poster child to its greatest cautionary tale:

He spent his childhood playing games like chess and bridge. His brother, Gabe, said, "playing games growing up, his inclination is if a board game is fun, you should play two simultaneous games at once with a timer."

Bankman-Fried studied physics at Massachusetts Institute of Technology where he juggled several extracurriculars alongside his academics. "I worked like an hour and a half a day in total and had trouble getting places on time," Bankman-Fried previously told BI. "I was a really negligent student."

During college, Bankman-Fried became especially interested in effective altruism, a philosophical movement that uses calculations to understand how people can use their time, money, and resources to best help others.

After college, Bankman-Fried went to work for the global trading firm, Jane Street. That's where he learned the art of arbitrage— a form of trading in which traders buy an asset for a low price in one market and sell it for higher in another market.

During his three years at Jane Street, Bankman-Fried would give away half of his salary to animal-welfare groups and effective altruism charities, according to Bloomberg. He left to work for MacAskill's Centre for Effective Altruism, set up by William MacAskill, one of the leaders of the effective altruism movement.

By 2017, crypto was booming, and people were trading on private exchanges. Bankman-Fried noticed that some coins were selling for higher prices on some exchanges than others. He realized he could use his arbitrage skills to exploit the gaps in prices.
