Custodial vs self-custody wallets

You are about to buy $100 of bitcoin through Coindisco. Before payment, you need a receiving address. There are two options in front of you: a deposit address on a crypto exchange and an address in your own wallet.

Where the bitcoin arrives shapes three things later: access to it, the cost of sending it and recovery after a lost phone.

The bitcoin arrives on a crypto exchange

Once the bitcoin arrives, it appears in your crypto exchange account balance. This is custodial storage: the platform holds cryptocurrency for you and handles your requests under its own rules.

The convenience is storage and trading in one place. A trade within the exchange needs no separate blockchain transfer. Sign-in, security settings and support are all part of the same crypto exchange account.

The other side is dependence on the platform. If the crypto exchange pauses withdrawals, the bitcoin stays on it until they resume. A hack or financial problems at the exchange also put customers' funds at risk.

The bitcoin arrives in your own wallet

In the second option, the purchase arrives in your own wallet. This is called self-custody. You manage the cryptocurrency yourself and take responsibility for keeping access to it.

The benefit is independence. Sending bitcoin needs no permission from an exchange and does not depend on its withdrawal rules.

The cost of that independence is responsibility. Protecting access and preparing for recovery are the owner's job. Selling on an exchange requires a transfer there first.

A week later, you need to send it

Now you want to send a friend half of the bitcoin you bought.

On a crypto exchange, sending is a withdrawal request. The platform processes it under its own conditions: minimum amounts, fees and possible checks all matter. For a small purchase, a fixed withdrawal fee may take a noticeable share of the amount being sent.

In your own wallet, you confirm a transfer that the Bitcoin network then processes. A network fee applies. Its size depends in part on demand for space in blocks.

A confirmed transfer to the friend's address cannot be reversed by the crypto exchange or by the wallet. Only the recipient can return the bitcoin.

Then you lose your phone

With a crypto exchange, the two-factor sign-in codes often come from an app on that same phone. Access to the crypto exchange account then returns through the platform's procedures, identity checks and support.

With a personal wallet, access usually returns through a recovery phrase: 12 or 24 words written down when the wallet was created. On a new phone, the phrase restores the wallet.

Losing a phone alone does not mean losing bitcoin. Losing the phone and every copy of the phrase may leave the funds permanently inaccessible.

The receiving address in Coindisco

Coindisco does not hold users' cryptocurrency. When buying, you choose the network and enter a receiving address from your own wallet or the deposit section of your crypto exchange account. The receiving wallet or crypto exchange must support the chosen cryptocurrency on that network.

An address can be saved and given a clear label, such as "Exchange" or "Personal wallet". On the next purchase, a saved address avoids retyping a long string of characters, while the label helps distinguish between several destinations.

Coindisco never asks for private keys, wallet passwords or recovery phrases.

Choosing before payment

For someone planning to trade on an exchange, receiving bitcoin directly at its deposit address reduces the number of transfers. A personal wallet gives control over bitcoin independently of a trading platform, along with responsibility for keeping access.

Before a $100 purchase, practical details matter: where you intend to use the bitcoin, what sending it costs and how to restore access if your phone is lost.

You spend $100 either way. How much bitcoin reaches the address depends on the offer you pick on Coindisco.
