BitMEX founder Arthur Hayes warned on May 1 that Bitcoin holders should not expect Michael Saylor to protect their BTC wallets, reinforcing the principle that custody responsibility ultimately falls on individual holders.
Hayes Puts Self-Custody Back in Focus
Hayes, who co-founded the cryptocurrency derivatives exchange BitMEX, directed his comments at those who may look to high-profile Bitcoin advocates as a safeguard for their holdings. His message was clear: no public figure, regardless of how much Bitcoin they accumulate on behalf of a company, bears responsibility for securing another person’s wallet.
The warning comes as Strategy, the company led by Michael Saylor, continues to expand its Bitcoin treasury. According to a May 18 press release, the firm acquired 24,869 BTC and now holds 843,738 BTC in total. That level of corporate accumulation can create the impression among retail investors that prominent holders are somehow protecting the broader market.
Saylor himself has previously taken positions that touch on custody transparency. He has argued that proof of reserves is a bad idea, a stance that adds nuance to the custody debate Hayes raised.
Why Public Advocacy Does Not Equal Wallet Protection
Saylor’s role as Bitcoin’s most visible corporate advocate has made him a central figure in how retail participants perceive institutional commitment to the asset. Strategy’s ongoing purchase history reinforces a narrative of long-term conviction that some holders may interpret as implicit support for their own positions.
Hayes’ point draws a line between public advocacy and personal security. A company buying Bitcoin for its balance sheet operates under its own risk framework, with its own custodial infrastructure. Individual holders who store BTC on exchanges or in poorly secured wallets cannot rely on any external party to recover lost funds.
The distinction matters especially as more retail investors enter the market. Cases where individuals have walked away from real estate to bet on Bitcoin gains illustrate how personal financial decisions around BTC carry risks that no corporate buyer can mitigate on a holder’s behalf.
What This Means for BTC Holders
The practical takeaway is straightforward: self-custody remains the only reliable method for securing Bitcoin. Hardware wallets, secure seed phrase storage, and personal key management are the holder’s responsibility, not a public figure’s.
Hayes’ comments also arrive during a period of shifting institutional flows. Earlier this year, Bitcoin ETFs experienced their heaviest weekly outflows since January, a reminder that institutional vehicles can move in either direction regardless of individual advocates’ stated convictions.
For holders weighing custody options, the message reinforces what Bitcoin’s design has always implied. The network is permissionless and self-sovereign by architecture. Proposals like the H.R.8957 strategic Bitcoin reserve bill may shape how governments interact with the asset, but at the wallet level, security starts and ends with the individual.
