Why the Private Key is so important

When you buy Bitcoin from an exchange or a bank and store it there, you do not own your Bitcoins. Exchanges and banks have total control because they own the private key to your Bitcoins. A Private Key is like a password - a sequence of letters and numbers - that you can use to access and manage your Bitcoins. Anyone who knows your Private Key can make transactions without your permission. Exchanges and banks withhold your Private Key so they can control your Bitcoins. In this case, your assets are exposed to severe privacy and security risks. In case of bankruptcy or hacking, you can lose everything. Numbrs eliminates this risk. Our Bitcoin Account is an institutional grade self-custody solution.

With the Numbrs Bitcoin Account your Bitcoins really belong to you and you alone. Only you own your Private Key, which is fully encrypted and secured in Switzerland. Our audited security systems are designed in a way that Numbrs cannot decrypt your private key and therefore has no access to your Bitcoins at any time. The Numbrs Bitcoin Account provides you with full control over your Private Key, so your assets are truly yours and fully protected.

The philosophy behind our Bitcoin Account

Wealth protection against inflation

Throughout history, the story of fiat currencies has always been the same. After their introduction, they are getting debased over time until they are rendered worthless. The very same process has recently accelerated due to the end of the gold standard, which decoupled fiat currency from any underlying collateral. Traditionally, investors hedged against this by spreading their risk across multiple currencies and safe haven assets like gold.

Bitcoin has changed everything by being free from any centralised control. Its supply is and its flows are independent from banks and nation states. For these reasons, Numbrs believes that Bitcoin will become the basis of a new monetary system and thus play a central part in long-term wealth preservation.

Bitcoin as the new gold standard

By its definition, Bitcoin’s supply is limited to 21 million coins. Since "lost" Bitcoins cannot be replaced, the actual number of Bitcoins in circulation will remain well below this number, even after all Bitcoins have been mined. In the long run, a growing number of the global population will want to own Bitcoin and its price will thus be driven up by immense demand and the unstoppable progress of technology.

Bitcoin's immutable supply, coupled with its fully decentralised, non-manipulable blockchain, make it a unique asset. The parallels to gold are obvious, but, unlike gold, Bitcoin can be easily transported in any quantity and transferred rapidly across the world. By combining the advantages of gold and decentralised cryptocurrency, Bitcoin represents its own asset class especially suited to long-term private investors.
