Biography
A digital trading pioneer, Thomas Peterffy chairs Interactive Brokers, which markets its specialized trading platform to sophisticated investors.

In March 2017, he announced part of his market-making operation would phase out. It had been under attack by faster competitors.
Peterffy arrived in America in 1965 at age 21, the penniless descendant of Hungarian aristocrats who lost nearly everything to the Soviets.
He is a major landowner, with more than 560,000 acres, primarily located in his home state of Florida.
Perspective on their fortune
Gold
Everyday luxury

A Thomas Peterffy's fortune is equivalent to 656 of gold, but this may be difficult to value, as we don't usually have a handful of gold bars in our piggy bank.

A standard gold ring typically weighs between 4 and 7 grams. Let's say this one weighs 5 grams. It's usually 18k gold.
Based on today's gold price (not taking into account the jeweler's fee, shipping, or anything else), that gold ring would be worth $556.3
Thomas Peterffy could buy 174,873,557 gold rings. That's a lot of fingers and a lot of gifts!!
And if the number of rings is difficult to visualize, all these rings would need 31 trucks to transport them, But we can be almost certain that Thomas Peterffy will have enough left over to pay for the gas for those trucks.
