Big players like Michael Saylor, the president of EI, or even some exchanges, i have been wondering how these guys store their BTC, their solutions, and their hardware storage.
Do any insiders know something? BTC
They do not really have more options than us, they are either using a hardware wallet or some sort of cold storage to secure their coins properly.
Now outside of the basics they could have additional security measures, like storing their hardware wallet in a safe or in a secret room and hire guards to keep their personal belongings safe, however while that can improve security those are measures that are not necessary for the average holder like us since it is unlikely we will be attacked if we keep the fact we accumulate bitcoin a secret.
No one really knows but we could really assume about the basics but of course with added security.
As a whale or does simply hold huge chunks of coins whether bitcoin and other altcoins in the market then you cant really just make yourself that too confident on storing up your
hardware wallet under your bed specially if you do know that it isnt something an amount that you would be comfortable with on just having that kind of security.
Some might be using up non custodial wallets and making out some engaraved PK's on a metal sheet and store it on whatever they do prefer
but no one really knows on how they've been doing in terms of the security of their coins.
