๐Ÿค– A16z crypto tested whether AI agents could hack DeFi on their own. Without prompting, only 10% of attacks were successful, but with a knowledge base of past hacks, the success rate increased to 70%.

The AI โ€‹โ€‹almost always found a vulnerability, but often failed at the most important stageโ€”building a working exploit. It got confused by multi-step schemes, miscalculated profits, and sometimes abandoned a working idea.

The conclusion is simple: AI is already greatly assisting in auditing and bug hunting, but complex DeFi hacks are still a human task.

๐Ÿ‡ฐ๐Ÿ‡ฟ In Kazakhstan, over 10,000,000 USDT frozen in the RAKS Exchange case โ€” one of the largest shadow crypto services in the CIS with a turnover of over $224 million.

According to AFM, transactions from over 200 drug markets from Kazakhstan, Russia, Ukraine, and Moldova passed through the exchanger โ€” as part of the investigation, 4000+ wallets were checked, and 3.2 million USDT has already been confiscated.

๐Ÿ‡ท๐Ÿ‡บ Russian officials reported that, according to the bill, Russians will be able to continue using crypto wallets in foreign services, but all operations will need to be reported to the Federal Tax Service (FTS).

In fact, such wallets are intended to be equated to foreign bank accounts โ€” with all tax and reporting consequences.

๐Ÿ‡ต๐Ÿ‡ฑ Polish crypto exchange Zondacrypto, which previously **announced** the loss of access to a wallet with 4,503 BTC, may be under the control of the "Tambov" organized crime group โ€” in 2018, representatives of the group acquired a controlling stake in the exchange, which at that time was called BitBay.

After privatization, the platform changed its name to Zondacrypto, and about โ‚ฌ18 million were transferred from the company's accounts to another exchange โ€” the prosecutor's office opened a criminal case on fraud and money laundering, and more than 30,000 people could have suffered from the exchange's activities.

๐Ÿ‡จ๐Ÿ‡ฟ The head of the Czech Central Bank supported the idea of adding BTC to central banks' strategic reserves, although he admitted that for the regulator, it is still an unusual and risky asset.

According to the bank's research, even 1% of Bitcoin in a portfolio can increase expected returns without a noticeable increase in overall risk due to low correlation with traditional assets.

Currently, the Czech Central Bank is already testing a small BTC portfolio over a two-year horizon.

๐ŸŒŽ The next 1 billion users will come to crypto not for trading, but through real-world use cases โ€” payments, income-generating products, asset tokenization, and AI.

The market is already showing a completely different scale: the supply of stablecoins has exceeded $320 billion, and the monthly on-chain transaction volume has reached 7.2 trillion.

According to Binance, this shift toward practical application could increase crypto's user base to 2 billion by 2030.

๐Ÿฆ‹ Crypto Bot is 5 years old today โ€” during this time, it has grown from a simple tool for crypto checks into one of the most convenient services for working with crypto directly in Telegram.

Today it includes checks, P2P, exchange, payments via Crypto Pay and other features that users and projects use daily.

Over these five years, the market has repeatedly gone through hype, drops, and new cycles, but Crypto Bot continued to develop and remain an understandable entry point into crypto.
