Bitcoin exchanges are moving to cut their quantum exposure before the network upgrades, a shift that puts 1.6 million BTC in custody at the center of the debate. Cryptoslate reported that the plan faces a real test: who controls those coins when quantum computers can crack today's signatures.
The custody question matters because exchanges hold coins on behalf of users. If quantum decryption arrives before a signature upgrade, those funds sit exposed. Moving to quantum-resistant addresses now would take coordination across the industry, but the window is narrowing.
Strive is buying through the uncertainty. The firm put $36.6 million into Bitcoin to reach 25,000 BTC, a milestone reported by The Block. That is a significant pile accumulated at a time when other treasury players are hesitating.
Strategy, by contrast, skipped a Bitcoin purchase for the second straight week. Instead, the company bought back $139 million of its STRC stock, according to Decrypt. The divergence shows two different bets on the same market, one adding to BTC, the other pulling capital back into equity.
**The bridge exploit that recovered 15 BTC**
Symbiosis recovered 15 BTC after a bridge exploit hit its Bitcoin bridge, and the bridge remains paused, per CryptoDaily. The recovery is a partial win, but the pause tells users that the vulnerability is not fully understood yet.
Bridge exploits in Bitcoin's ecosystem often exploit the way wrapped assets move between chains, and each incident narrows the list of safe routes.
Options traders flip bullish
Bitcoin options traders turned bullish for the first time in 12 months, according to News.Bitcoin. That shift in positioning suggests the derivatives market is pricing in upside rather than protection. When calls start outpacing puts at these volumes, it often means large players expect a move up, not down.
**Swiss Bitcoin Pay shuts down after suspected breach**
Swiss Bitcoin Pay shut down its servers after a suspected breach, as Crypto Briefing reported. The company took its systems offline rather than risk further exposure. For a payments processor, that decision is a signal that the threat felt real enough to stop operations entirely.
What to watch
Strive's 25,000 BTC position and Strategy's frozen stack will stay in tension as long as treasury strategies diverge. The options market's bullish flip and the bridge recovery both point to a sector still absorbing risk rather than fleeing it.
The quantum upgrade timeline is the bigger story underneath all of this, once it lands, custody rules change for everyone holding Bitcoin.
