What is Bitcoin Self-Custody?

Aligned with the needs of sophisticated private investors, we have built Bitcoin Self-Custody, an institutional grade self-custody solution to store Bitcoin in a high security military bunker. The core value proposition of Numbrs is not trading but rather to guarantee the secure and discreet self-custody storage of Bitcoin in Switzerland. The features include:

Own your Bitcoin

If you do not own your private keys, you do not own your Bitcoins. With Bitcoin Self-Custody, your private keys and therefore your Bitcoins belong only to you and you alone (see more information on private keys and self-custody here). Not even Numbrs can access your private keys.

Backup in Switzerland

A fully encrypted backup in Switzerland guarantees comprehensive protection of your Bitcoins. If you lose your password or seed phrase, you can recover your Bitcoins from your backup hosted in Switzerland.

Send and receive Bitcoin

With Bitcoin Self-Custody, you can send Bitcoin to any recipient in the world. No settlement times of several business days, no additional fees for international payments, no minimum or maximum amounts.

Pay in Bitcoin

Whether it is to pay for hotels, shopping or automobiles, many merchants are accepting Bitcoin around the world. In addition to Bitcoin Self-Custody, the complemantary app enables you to pay with your Bitcoins.

Customer service - 24/7

Bitcoin Self-Custody holders have access to anexclusive customer support at any time of the day. Our experienced agents will assist you through a communication channel of your choice.

Backed up in Swiss military bunker

Your private key is backed up fully encrypted in a military bunker at a maximum security facility within the mountain massifs of the Swiss Alps. As a Bitcoin Self-Custody client, you can securely restore your private keys, in case of loss.

Swiss Company. Swiss Shareholders.
