The ongoing Coldcard wallet exploit has now resulted in the theft of more than $100 million worth of Bitcoin, according to Galaxy Research. While the scale of the attack continues to grow, some analysts believe the stolen funds may prove difficult to cash out because every transaction can be traced on Bitcoin\u2019s public blockchain.<\/p>\n\n\n\n

Market commentator Joe Consorti argued that the incident highlights one of Bitcoin\u2019s defining characteristics. Although attackers can steal private keys, the movement of stolen coins remains visible to blockchain analysts, exchanges, and law enforcement agencies.<\/p>\n\n\n\n

Stolen Bitcoin Remains Closely Monitored<\/strong><\/p>\n\n\n\n

In a post on X, Consorti said the attacker would likely face significant challenges trying to spend the stolen Bitcoin because the assets are being tracked by Galaxy Research, the FBI, and numerous blockchain investigators.<\/p>\n\n\n\n

He went as far as describing Bitcoin as one of the least practical forms of money for criminal activity due to its transparent ledger.<\/p>\n\n\n\n

Consorti also stressed that the exploit did not compromise the Bitcoin network itself. Instead, the vulnerability originated in Coldcard wallet firmware released after March 2021, which generated wallet seed phrases with insufficient randomness.<\/p>\n\n\n\n

As a result, even users who followed recommended self custody practices became vulnerable because the software produced weaker than intended recovery seeds.<\/p>\n\n\n\n

Galaxy Research has identified 1,596 BTC stolen across roughly 7,300 wallet addresses in three confirmed attack waves. Including suspected but unverified incidents, total losses could reach 2,055 BTC, currently valued at more than $130 million.<\/p>\n\n\n\n

The firm said approximately 90 percent of the stolen Bitcoin remains untouched, with all funds from the first three confirmed attack waves still held in wallets controlled by the attacker. Galaxy has already shared confirmed wallet addresses with US law enforcement agencies, cryptocurrency exchanges, and blockchain forensic firms.<\/p>\n\n\n\n

Despite the high profile theft, Bitcoin continued to trade near $64,000, rising about 2 percent over the previous 24 hours. Consorti pointed to the market\u2019s resilience as evidence that investors distinguish the wallet security flaw from the Bitcoin protocol itself.<\/p>\n\n\n\n

The first confirmed theft was detected on July 31, when 594.5 BTC was drained from roughly 500 addresses across four blocks. Coinkite, the company behind Coldcard, later confirmed that affected wallets were created using seeds with about 72 bits of entropy instead of the intended 128 bits, making them vulnerable to brute force attacks with sufficient computing power.<\/p>\n\n\n\n

The company has since released updated firmware to fix the issue going forward, but previously generated wallet seeds cannot be repaired. Owners of Mk3, Mk4, Mk5, and Q devices have been urged to transfer their Bitcoin to secure wallets created on unaffected hardware.<\/p>\n\n\n\n

Community Split on Whether the Funds Can Be Laundered<\/strong><\/p>\n\n\n\n

Some industry observers share Consorti\u2019s view that spending such a large amount of stolen Bitcoin will be extremely difficult. Crypto commentator Shagun argued that blockchain surveillance, compliance checks, and the risk of operational mistakes make laundering the funds far more challenging than stealing them. Shagun even suggested the attacker should consider returning the Bitcoin in exchange for a negotiated bug bounty.<\/p>\n\n\n\n

Others disagree, arguing that privacy tools could still provide possible escape routes. They point to cryptocurrency mixers, privacy focused networks, Taproot transactions, and the Lightning Network as methods that could potentially help obscure the movement of the stolen funds.#crypto#cryptonews https:\/\/coinsignals.net<\/a> https:\/\/t.me\/coinsignalpublic<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
