Bitcoin: Be Your Own Bank | T-Shirt

“Bitcoin: Be Your Own Bank” is a metaphor for holding bitcoin without a custodian; it does not mean a wallet replaces banking services. Under Self-Custody, Private Key Control allows a user to authorize spending through Transaction Signing. For seed-based wallets, resilience requires a verified Seed Phrase Backup, appropriate Cold Storage, and ongoing Personal Responsibility. Bitcoin reduces dependence on intermediaries, but does not eliminate risk: theft, signing errors, or lost recovery data can make funds inaccessible.

Printed on a Bella+Canvas 3001 Unisex Jersey T-Shirt.

Frequently Asked Questions

What does Be Your Own Bank mean in Bitcoin?
In this design, the phrase is a metaphor for self-custody: holding the private keys needed to authorize spending without relying on a custodian. It does not mean a Bitcoin wallet provides deposit insurance, credit, account recovery, or every other service supplied by a bank. Self-custody changes who controls the keys and who bears the operational responsibility.

What does controlling private keys actually allow?
For common Bitcoin outputs, private keys create digital signatures that satisfy the conditions for spending. Wallet software manages keys and constructs transactions; it does not hold bitcoin as a file inside the device. Whoever obtains enough valid signing material may be able to spend the funds, while losing the only usable keys or recovery data can make them inaccessible.

What responsibilities come with self-custody?
Self-custody requires protecting key material and recovery data, verifying recipient addresses and amounts before signing, and maintaining a recovery plan appropriate to the value and threat model. A hardware wallet can keep signing keys off a general-purpose computer, but it cannot repair a bad backup, undo a mistaken transaction, or protect a recovery phrase that has been exposed.

Where are the designs printed?
The T-Shirt has a small Be Your Own Bank graphic on the left chest and a larger Bitcoin character design on the back, as shown in the product images. Review both print placements and your selected color before ordering.

How do I choose the right size?
Lay a similar T-Shirt that fits you well on a flat surface and compare its width, length, and sleeve length with the product-specific size chart. Choose using garment measurements rather than your usual label size, and allow for the listed +/- 1.5 in manufacturing tolerance.
