Physical violence is the final vulnerability in Bitcoin security. Attackers know they can demand a seed phrase and have funds moved within minutes. According to Max Guise on TFTC, time is the critical defense. He argues most robberies last less than 24 hours, so a vault that imposes a one-week withdrawal delay destroys the attacker's incentive to wait. The target shifts from hiding a balance to making the funds impossible to move fast.
Guise described new hardware features designed for this. Bitkey’s latest device includes a screen to physically verify account changes, creating a barrier against phishing. If a thief does steal keys and wait out the timer, the system can automatically eject funds to a safe secondary wallet once the lock expires.
“Making money slow to move is the only way to stop fast violence.”

Ease of use is a parallel security challenge. Long checklists and seed phrase management often scare people away from leaving exchanges. Guise argues the portable, instantly-usable seed phrase is itself a liability during a robbery. Bitkey uses a 2-of-3 multisig system involving hardware, a phone, and Block’s servers to remove that friction, aiming to make setup simple enough to finish in minutes while making theft much harder.
Meanwhile, other companies are building the rails to make held Bitcoin useful without moving it at all. On Bitcoin 2026, Jack Mallers of Strike detailed a merger with Tether’s mining arm to create what he calls the Ideal Bitcoin Company. A key product is volatility-proof loans, backed by a $2.1 billion Tether facility, which let users borrow against Bitcoin without fear of liquidation from a market crash.
Block is attacking the spending problem from the merchant side. Miles Suter, also on Bitcoin 2026, explained that Block auto-enabled Bitcoin acceptance for 800,000 Square merchants. To avoid tax complexity, Block’s “Dollars on Lightning” feature lets users pay over the Lightning Network using a dollar balance. The goal is to make Bitcoin function as cash, not just a stored asset.
“If the network doesn't function as peer-to-peer electronic cash, it loses its transformational edge.”

The industry is converging on a dual solution: protect the stack from physical theft with time-locked vaults, and build financial infrastructure that unlocks its utility without ever needing to move it.
