The original AWAG articles explain the basics of cryptocurrencies and wallets. At the practical level, the most important distinction is between owning an asset and handling its access and transfer safely.
A wallet manages access—not the asset itself
Digital assets remain on a network. The wallet manages the keys and instructions that allow a person to receive or transfer them. This distinction matters because losing access credentials can be very different from losing a bank password: depending on the wallet model, there may be no central provider able to restore access.
Custody changes the responsibility
A hosted wallet places part of the operational responsibility with a provider, while a self-custody wallet gives the user direct control of the keys. Neither model is automatically right for everyone. The decision should reflect technical confidence, transaction frequency, recovery planning and the consequences if a device or credential becomes unavailable.
Every transfer deserves a pause
Addresses are long, networks can differ and transfers may be irreversible. A careful routine includes confirming the correct network, checking the destination independently and using a small test transfer when the amount or context justifies it. Urgency is a warning sign—especially when instructions arrive through an unexpected message.
What this means in practice
Wallet choice is ultimately a decision about responsibility. The right model is the one whose recovery, verification and security routines can be followed consistently—not only when everything works, but also when access, devices or instructions become uncertain.
Frequently asked questions
What is the practical difference between custodial and self-custody wallets?
A custodial provider controls the keys and manages access processes. With self-custody, the user controls the keys and is responsible for secure recovery and verification.
Can a blockchain transfer usually be reversed?
Usually not. That is why the destination address and network should be checked independently, with a small test transfer considered for unfamiliar or high-value transactions.
