Polish Cryptocurrency Exchange Hit by Ponzi Scheme, Former CEO Disappears with 4,500 Bitcoins Private Keys

2026.05.05 10:45:28

On May 5, Polish crypto exchange Zondacrypto is under a major fraud investigation. Its former CEO went missing in 2022, taking the cold wallet private key holding 4,500 bitcoins—currently worth over $340 million. The current CEO has admitted he can’t access the wallet and was recently reported to have fled to Israel. Prosecutors estimate potential customer losses at roughly $97 million. On-chain data shows the exchange’s hot wallet bitcoin balance has plunged 99.7% since mid-2024, with users widely reporting withdrawal issues. Polish Prime Minister Tusk estimates up to 30,000 users may be affected. Tusk publicly accused the exchange of being funded by Russian-linked entities and used to back opposition lawmakers in blocking crypto regulation in Poland. He bluntly labeled it a “Polish Ponzi scheme” and criticized the president for twice vetoing the localization bill of the EU’s MiCA framework, turning Poland into a “haven for fraudsters.” The exchange’s board of directors said they’ve been unable to get “verifiable information” from the missing CEO and have collectively resigned. The founder, who’s been missing since 2022, remains under investigation over prior “kidnapping allegations.” The incident is expected to push Poland and the EU to tighten regulatory oversight of crypto exchanges.

Peter Schiff: SEC’s Innovation Exemption for Tokenized Stocks Is Bad for Bitcoin

Longtime Bitcoin critic Peter Schiff argued in a post that Bitcoin’s sharp surge following the U.S. Securities and Exchange Commission (SEC)’s announcement on tokenized stocks is meaningless. In reality, this news is bearish for Bitcoin, as the cryptocurrency now has to compete with tokenized securities. Tokens backed by profitable, dividend-paying companies hold an advantage over asset-less tokens in terms of digital ownership, and are also more reliable stores of value. Tokenized stocks offer all the conveniences of Bitcoin while eliminating the risk of a decentralized Ponzi scheme collapse.

CZ responds to KOLs who called GSTOCK trades nine times this week, with the token price surging nearly threefold to hit a new all-time high.

Binance founder CZ today responded to crypto KOL Jasmy, stating, "The idea of acquiring a listed company via a meme is definitely not something I came up with." Notably, the KOL’s posts on X this week have all centered on GSTOCK, totaling 9 buy calls. According to GMGN market data, GSTOCK has just hit an all-time high, with a current market cap of $20.74 million; earlier this morning, its market cap once dropped below $7 million. The GSTOCK token is paired with BNCB—the on-chain token of BNB treasury firm BNC—as its liquidity pool base. Genius Terminal, an on-chain trading terminal invested by YZi Labs and with CZ as an advisor, previously announced the official launch of its token issuance platform genius.fun on BNB Chain. The platform allows creators to transfer tokenized stocks such as bSTOCKS to a public foundation and split them, then attempt to exercise equity-related rights off-chain. BlockBeats reminds users that relevant token prices are highly volatile, so caution is advised for investments.
