Whoever controls the private keys controls the Bitcoin. This is a plain guide to custody risk in South Africa, from an exchange balance you do not truly own, up to a managed 2-of-3 multisig vault built for significant holdings. You hold the keys.
Not sure which level is right for you? Start with the spectrum below, then talk to us before anything is built.
Unlike a bank account, Bitcoin has no custodian standing behind you unless you choose one. There is no branch to call and no reversal. Possession of the private key is ownership, which is the freedom of Bitcoin and also the responsibility.
The fix is to choose the right level of custody for the size of your holding and the people who depend on it, then set it up carefully and document it. That is what the spectrum below is for.
Each step up trades a little convenience for a lot of resilience. There is no shame in starting low and growing into a higher level as your holding grows. We would rather point you to the right level than sell you a structure you do not yet need.
The most common starting point and the weakest form of ownership. The Bitcoin sits with a third party, so you hold a claim rather than the asset, exposed to collapse or a frozen account.
Fine for short-term trading, never for long-term holdings.Your first real step into self-custody. A phone or desktop app gives you the private keys and a seed phrase you must record and protect. The keys still touch an internet-connected device.
Good for smaller amounts you use regularly.A dedicated device such as a Trezor, Ledger or Coldcard keeps your keys offline and away from malware. You still carry the single point of failure of one device and one seed backup.
A solid foundation for a growing holding.Adding a passphrase, the so-called 25th word, creates a hidden wallet on top of your seed. The passphrase is useless on its own, so it can be stored separately for a strong extra layer.
Enhanced protection without full multisig complexity.Three keys on three devices, any two of which are needed to move funds. No single device is a point of failure, and no single party can act alone. Powerful, and genuinely technical to run yourself.
For serious holdings, if you have the technical appetite.The security of multisig without the technical burden. You hold two keys, we hold one recovery key, and legacy planning is built in from day one. We can never move your Bitcoin on our own.
For significant holdings, companies, trusts and family offices.The SimplB Vault is a 2-of-3 multisig built on three hardware devices from three manufacturers. You generate and hold two keys yourself, we never see or touch your seed words, and we hold the third key on an air-gapped device purely for recovery and inheritance. Any two keys move funds, so your own two keys let you transact without us, and we can never act alone.

Good security is not only about keeping Bitcoin away from thieves. It is about making sure the right people can reach it when you no longer can. Whatever level you choose, sound legacy planning rests on four things.
In a managed vault we build a dedicated path for heirs into the setup itself. See also what happens to your Bitcoin when you die in South Africa.
South African holders carry considerations that global guides skip: FSCA oversight of crypto asset providers, SARB exchange control, FIC obligations, and how a company or trust should govern who can move the coins. Because you physically hold the majority of the keys, the Bitcoin stays a locally domiciled, self-custodied asset rather than a balance on someone else's books.
SimplB helps South Africans buy, secure and structure Bitcoin as a Juristic Representative of CAEP Asset Managers (FSP 33933), and is a member of the Crypto Asset Association of South Africa. Our security work is administrative and educational in nature: wallet setup, self-custody infrastructure, onboarding support and documentation. Regulated financial services are rendered through CAEP Asset Managers under their FSP licence. Nothing on this page is financial advice.
The right approach depends on how much you hold, how technical you want to be, and who depends on the Bitcoin after you.
A software wallet is a fair first step for smaller amounts you use regularly, once your seed phrase is written down and stored offline.
A hardware wallet with a passphrase gives strong protection without the full complexity of multisig, ideal as your position grows.
A managed 2-of-3 vault gives institutional-grade security with support and legacy built in, for holdings, companies and trusts.
For a meaningful holding, a 2-of-3 multisignature setup is the strongest practical option, because no single key can move funds and losing one key does not lose the Bitcoin. Smaller amounts can start on a single hardware wallet with a steel seed backup. An exchange balance is the least safe place for anything you intend to hold.
No. In a managed vault you hold two of the three keys and we hold one, purely for recovery and inheritance. Any two keys are needed to move funds, so we can never act alone, and your own two keys let you transact without us. It is self-custody with support, not custodial.
In a single-key setup, losing the seed usually means losing the Bitcoin. In a 2-of-3 vault, one lost key is a Tuesday: the remaining two keys keep the Bitcoin safe and reachable while the missing device is rebuilt from its backup.
Only if you plan for it. We build a documented inheritance path into the vault setup, with clear access instructions for your heirs or executor, so the Bitcoin does not become unreachable. This is a core reason larger holders move to a managed vault.
Yes. Self-custody is legal, and holding the keys yourself keeps the Bitcoin a locally domiciled asset in your name. SimplB operates as a Juristic Representative of CAEP Asset Managers (FSP 33933), with regulated services rendered through CAEP, so your setup sits inside a compliant structure.
