What is self-custody?
When you buy or store Bitcoin with custodial exchanges such as Binance, Coinbase or Celsius, they have full control over your assets. This is because they control the private key to your Bitcoin. Until you withdraw your Bitcoin to a self-custody storage solution, you have no control over your private keys, which exposes your assets to severe privacy and security risks. In the case of bankruptcy, hack or confiscation, you can lose everything.
Numbrs is a self-custody solution that gives you complete control over your Bitcoin. A self-custody solution is made for clients that have understood the full potential of Bitcoin and want to take advantage of it. For Numbrs, this is a matter of principle. Bitcoin was created to give people control over their money. Individual sovereignty is the idea that brought us into the Bitcoin space in the first place. This principle is in our DNA. That is why we offer the world’s best offline storage solution for sovereign individuals.
What are the advantages of self-custody?
With Numbrs, your Bitcoin belongs to you and you alone. Your private key is fully encrypted and secured in Switzerland and you are the sole owner of your Bitcoin, granting you complete independence from banks and third-party influences.

What is Offline Storage?
Offline Storage means that the server on which your Bitcoin is stored, is completely offline. Offline storage is used to store digital currencies for the long term. By definition, offline storage is a form of storage that is never connected to the internet. It is the equivalent of storing assets in a bank vault.
