Investing.com -- Bitcoin traded above $63,000 on Sunday, rising slightly over the previous 24 hours as the market absorbed expanding Coldcard wallet losses and further Bitcoin sales by Trump Media & Technology Group.
Losses linked to a vulnerability in Coldcard hardware wallets have reached 1,367 Bitcoin, worth nearly $89 million, according to Galaxy Research. Bitcoin was trading at $63,526.0 as of 17:00 ET (21:00 GMT) registering a 1.38% gain.
A third round of transfers drained approximately 208 BTC from 1,912 addresses between Friday afternoon and Saturday morning. Across all three waves, funds have been removed from 4,585 addresses.
The first attack on July 30 took 1,083 BTC from 1,196 wallets in 41 minutes. The latest transactions targeted smaller balances and used a different method to collect funds, raising the possibility that the original attacker changed tactics or another operator began searching the same vulnerable keys.
The flaw originated in a March 2021 firmware release that used a predictable software randomiser when generating wallet seeds rather than the device’s hardware system. Attackers can reproduce possible private keys offline without accessing the physical wallets.
Trump Media & Technology Group Corp (NASDAQ:DJT) was reported to have sold another 2,628 BTC worth about $165 million, according to blockchain analytics account Lookonchain. However, a Trump Media spokesperson clarified on Sunday that the BTC was transferred to Crypto.com, not sold, The Block said.
The company has reportedly sold 7,281 BTC after initially purchasing 11,542 coins for about $1.37 billion, representing an average cost of $118,522 per coin.
Its remaining 4,260.73 BTC is pledged as collateral against convertible notes until no later than May 2028. Lookonchain estimates Trump Media’s realised and unrealised Bitcoin losses at roughly $555 million.
Strategy Inc (NASDAQ:MSTR), the largest corporate Bitcoin holder, maintained the August dividend on its STRC preferred stock at 12%. The company had previously raised the payout when STRC traded substantially below its $100 par value.
STRC currently trades around $89.46, recovering from a June low near $71 after the July dividend increase and some stabilisation in Bitcoin.
Beyond corporate treasuries, Bitcoin ownership is increasingly shifting towards exchange-traded funds, financial institutions and governments. Spot Bitcoin ETFs earlier recorded more than $220 million in inflows following a period of sustained withdrawals.
The growing institutional presence may provide a longer-term source of demand, though wallet-security concerns and corporate sales could limit near-term momentum.
