MANTRA price falls as trading activity increases

MANTRA traded near $0.0045 at the time of writing, falling approximately 9.8% over 24 hours, according to CoinGecko data. Its seven day decline reached about 12.8%.

Trading volume rose by roughly 591% to more than $22.7 million. The increase shows greater market activity but does not establish whether every transaction was a direct response to the network shutdown.

The token reached a 24 hour low near $0.00413. Its market capitalization stood at approximately $27.8 million, based on CoinGecko’s estimated circulating supply of 6.3 billion tokens.

The current MANTRA token followed a March 2026 rebrand and denomination change. As previously reported, the project completed a one for four token split, replacing the former OM ticker without changing holders’ proportional value.

That change means current prices cannot be compared directly with the legacy OM price without adjusting for the split. The original OM token separately lost more than 90% during its 2025 collapse, which the project attributed to forced exchange liquidations. Other researchers questioned that explanation.

MANTRA said it would keep the network offline until its teams confirm that a restart is safe. Users must wait for an official root cause assessment, recovery plan and notice that validators and exchange transfers have resumed.

HTX Creation Challenge — Post and Win 1,500UHTX 13th-Anniversary Carnival The U.S. Department of Justice has expanded its case against members of the Iran-based Mabna Institute, adding charges against

The U.S. Department of Justice has expanded its case against members of the Iran-based Mabna Institute, adding charges against eight individuals and linking five of them to the 2017 hack of HBO that included a ransom demand of roughly $6 million in Bitcoin. The new indictments bring the total number of defendants in the broader cyber-espionage case to 17.

Details of the HBO Hack and Indictment

According to the DOJ, Behzad Mesri was previously indicted separately for allegedly hacking HBO’s systems, stealing internal data, and demanding a Bitcoin ransom of about $6 million. The latest charges allege that five of the newly charged defendants directly participated in that operation alongside Mesri. The Mabna Institute is accused of conducting cyberattacks against U.S. and international universities, companies, and government agencies on behalf of Iran’s Islamic Revolutionary Guard Corps (IRGC) and other entities.

Broader Context of Iranian Cyber Operations

The Mabna Institute has been linked to a series of intrusions dating back to at least 2013, targeting over 300 universities in the U.S. and abroad. The group’s activities have been characterized by U.S. officials as systematic theft of intellectual property and sensitive data. The new charges underscore the ongoing threat posed by state-sponsored hacking groups and the increasing use of cryptocurrency in ransom demands.

Implications for Cybersecurity and Crypto Regulation

This case highlights the intersection of cybercrime and digital currencies, as Bitcoin’s pseudonymous nature has made it a preferred payment method for ransomware attacks. The DOJ’s actions signal a continued effort to hold state-sponsored hackers accountable, even when they operate from jurisdictions with limited extradition treaties. For businesses and institutions, the case serves as a reminder of the persistent risks of cyber intrusion

Bitcoin, ether and solana climb as another $1 billion shorts get wiped outBitcoin rose to just under $75,000 in Asian morning hours on Friday, up almost 8% on the day and nearly 18% over the week, after touching just above $75,500 overnight. Two days ago it traded near $64,100.

Short sellers took another beating, as roughly $1 billion of short positions were liquidated over 24 hours out of $1.23 billion in total, across 140,416 traders, per CoinGlass.

That follows the $3 billion of shorts wiped out on Thursday, the largest single-day figure in records going back to 2021, bringing the two-day total to more than $4 billion. The largest individual position closed in the latest session was a $25.13 million bitcoin trade on Hyperliquid.

A liquidation happens when a trader borrows to make a bigger bet than their money would cover, the market moves against them, and the exchange closes the position automatically before the losses exceed what they put down. These were traders betting the price would fall, and each forced closure pushed prices up and created a cascade of liquidations.

The size of the number matters because it separates a rally built on demand from one built on mechanics. Traders forced to buy are not deciding bitcoin is worth more; they are covering a losing bet.

Meanwhile, Hyperliquid's HYPE rose over 4% to nearly $73 and leads the majors on the week at almost 27%. Ether added almost 5% to $2,350 and is up 24.5% over seven days. Dogecoin gained almost 9% to just over 8 cents and solana over 5% to just under $90, both up 17% on the week.

BNB rose 6% to $660 and is up 8% over seven days. Tron lagged, up 1.5% to just under 34 cents and barely moved on the week.

The rally traces back to Wednesday, when the Treasury doubled the size of its long-end bond buybacks from $2 billion to $4 billion per operation, easing conditions across the roughly $30 trillion Treasury market and lifting appetite for risk.
