Welcome to the Millionaire Club

About 40 percent of those between 24 and 35 have at least $1,000 in their savings account. That may not sound like that much, but 19-year-old bitcoin millionaire Erik Finman says that's enough to invest in cryptocurrency.

The teenager has had some luck with the cryptocurrency growing up: At age 12, Finman used a $1,000 gift from his grandmother to buy his first bitcoin and by 18, he became a millionaire. He currently owns 401 bitcoins, which equals $3.4 million at a rate of $8,512 a coin.
