Cryptocurrency exchange Coinsbuy is offering a $100,000 reward for information leading to the arrest of the hackers behind Sunday's security breach. The exchange has confirmed that all affected client funds have been fully covered, even as an onchain investigator estimates that more than $7.9 million was stolen in the incident.

Exchange Moves to Reassure Users

In an official statement released on Monday, Coinsbuy acknowledged the unauthorized withdrawals that occurred on Sunday, but stressed that no customer has been left out of pocket. The company said it has already reimbursed all impacted accounts, using its own reserves to cover the losses.

“We take full responsibility for this incident,” a spokesperson said. “Our priority is the safety of our users’ assets, and we are doing everything in our power to ensure this never happens again.” The exchange also hinted at enhanced security measures, including a full audit of its systems, though specifics have not yet been disclosed.

Onchain Investigator's Estimate

Independent blockchain sleuths have been tracking the stolen funds since the attack. One prominent onchain investigator, who wished to remain anonymous, placed the total losses at $7.9 million in various cryptocurrencies. The investigator noted that the funds have been moved through several mixing services, making recovery difficult.

Coinsbuy has not officially confirmed the exact amount, but has not denied the estimate either. The exchange’s reward offer is aimed at incentivizing anyone with information about the perpetrators to come forward.

The $100K Bounty: A Growing Trend

Offering a reward for information leading to the arrest of cybercriminals is becoming a common tactic in the crypto space. Several exchanges have adopted this approach in recent years, hoping to deter future attacks and demonstrate their commitment to law enforcement cooperation.

Coinsbuy's bounty is among the largest ever offered by a mid-sized exchange. The company has urged anyone with relevant information to contact its security team or local authorities. The reward will be paid in cryptocurrency or fiat, at the winner's discretion.

  • Reward amount: $100,000
  • Estimated stolen funds: Over $7.9 million
  • Incident date: Sunday, August 9, 2026
  • Status: All affected clients reimbursed

Security Concerns in the Crypto Industry

This breach serves as a stark reminder of the persistent security challenges facing cryptocurrency exchanges. Despite advances in encryption and multi-signature wallets, hackers continue to find vulnerabilities in centralized platforms.

Industry experts argue that exchanges must adopt more robust security protocols, including cold storage for the majority of funds, regular third-party audits, and real-time anomaly detection. Some also advocate for decentralized exchanges (DEXs) as a safer alternative, though they come with their own set of risks.

What Users Should Do

For Coinsbuy users, the immediate risk appears to be mitigated, but it's always wise to take precautions. Consider enabling two-factor authentication (2FA) and withdrawing large amounts to a personal hardware wallet. Stay alert for phishing attempts, as scammers often exploit security incidents to trick victims.

Key Takeaways

  • Coinsbuy has offered a $100,000 reward for information on the hackers.

As the investigation continues, the crypto community will be watching closely. Will the bounty lead to arrests? Can Coinsbuy restore trust? Only time will tell, but one thing is certain: the industry's battle against cybercrime is far from over.
