As crypto continues to move into the mainstream, so too do the threats surrounding it.

Speaking at the Trustless by Design conference in Prague - an exclusive event where BitDegree was invited as a special guest - Matěj Žák, CEO of Trezor, drew attention to an unsettling reality: the crypto industry's success attracts increasingly sophisticated hackers.

"Just recently we experienced the Bitcoin BTC $108,181.14 all-time high. But hackers had their all-time high as well," he remarked during his keynote.

One of the most striking examples, Žák noted, was the Bybit $5.04B hack, which took place in February 2025. In was one of the largest crypto thefts in history, where hackers linked to North Korea stole around $1.5 billion worth of Ethereum ETH $3,854.56 from the Bybit crypto exchange.

He said that the scale of the theft exemplifies how centralized exchanges have become "massive moneypots" for cybercriminals, and that the threat isn't going away anytime soon:

Security is a moving target.

Žák's message was that as long as large sums of digital assets remain concentrated in centralized systems, hackers will continue to find ways to exploit weaknesses. As a solution, he urged users to embrace self-custody and store their digital assets in hardware wallets rather than on exchanges.

To that end, Žák concluded his address by announcing the Trezor Safe 7, the company’s most advanced hardware wallet yet. What is special about this wallet? Read the full story here.
