ZachXBT, an on-chain investigator, has announced a $10,000 bounty for credible information on Heisenberg Guru, also called HSBG, a Hong Kong-based market maker allegedly involved in various cases of centralized exchange (CEX) market manipulation, including the $RIVER token.
According to a message posted on Telegram, ZachXBT said the bounty applies to verifiable evidence like chat logs, contracts, internal communications, or other documents that could support allegations of manipulative trading activity.

The message stated, “Offering up to a $10k bounty for intel about Hong Kong market maker Heisenberg Guru, aka HSBG, linked to multiple CEX market manipulation incidents such as $RIVER.
Heisenberg Guru draws scrutiny
Heisenberg Guru (HSBG) has found itself under fire due to some suspicious activities involving the pricing of some of its tokens. Of note is the $RIVER token, which has become the center of attention in a case of suspected market manipulation through coordinated trading actions that could have affected the prices at leading exchanges.
Although the nature of the manipulation has yet to be determined, the case has attracted the attention of the crypto community amid growing concerns over wash trading, spoofing, and other deceptive practices on centralized platforms.
$RIVER token price context
At the time of this writing, River ($RIVER) is trading at $7.64, up 5.13% in the past 24 hours, showing a strong momentum, according to CoinMarketCap. The 24-hour volume has reached $24.59 million, around a 59.14% increase.Â
Regardless of this surge, $RIVER is still around 91.3% down from its all-time high of $87.79 recorded in January 2026. However, the token has shown recovery from its all-time low of $1.14 set at launch in September 2025.
With only 19.6 million tokens in circulation out of a 100 million total supply, market capitalization stands at $149.83 million. The sharp price action indicates high volatility and continued speculative interest in the token.
Prior manipulation allegations
ZachXBT has previously reported a series of such events prevailing in the crypto market. Recently, the investigator released the most elaborate report on the LAB token to date, surpassing the earlier allegations of price manipulation.Â
The allegations included the use of a BVI shell company, hidden private loans, and one-sided modifications of token vesting terms. Moreover, the report highlighted on-chain links between the LAB token and the newly scandalized $RIVER token. According to the ZachXBT investigation, insiders seem to own more than 95% of the token supply.
Market integrity remains at stake
The cryptocurrency sector is still struggling with the problems of market integrity. The regulators are becoming stricter towards manipulation in the industry, yet the implementation of any measures proves to be difficult because of the pseudonymity of blockchain transactions and the international operations of many trading companies.
With the further developments in the case, everyone will watch how successful the reward of $10,000 will be in producing tangible evidence against Heisenberg Guru. It may affect not only the parties involved in the case but also the overall reputation of the centralized exchange market. ZachXBT did not say when exactly the deadline for the bounty ends or what its terms are.
