Niall Leonard discovered $1.5 million stolen in his Bitcoin, AnotherDay and Paxful Holdings

A thief on the blockchain steals $1.5 million in cryptocurrency from investors.

A crypto investor says that $1.5 million of his stolen money ended up in an account at a cryptocurrency exchange in Manhattan, and he wants to know how this happened.

A Manhattan Supreme Court filing says that in May, corporate quality expert Niall Leonard found that his Bitcoin and other cryptocurrencies had all of a sudden disappeared from his digital wallets.

Leonard, an Irishman who lives in Qatar, hired the British financial investigation firm AnotherDay right away. They tracked the money to an account with a Koreatown company called Paxful Holdings.

Paxful would not give out the account holder's name without a court order. Leonard wants a judge to make Paxful say who has the stolen money.

A Paxful spokesperson told The Post that the company is "working hand-in-hand with Niall Leonard's team" and is "doing everything in our power to provide transparency" while following U.S. law.

In an email to The Post, a spokesperson said, "We're waiting for the next steps and will work with law enforcement to make sure anyone who did something wrong is brought to justice."
