Plain-language explainers of how crypto works, with the caveats kept in.
There is no single best crypto wallet in the UAE. The right one depends on whether a licensed firm holds your coins or you hold your own keys. This guide explains the UAE rules, the main wallet types, and how to choose.
Bitcoin's code caps the supply at 21 million coins, and about 20.1 million are already mined. Here is how many are left, when the final coins arrive near 2140, and what miners will earn once the block rewards run out.
A DAO lets strangers pool money and run a project through code, not a CEO. Members vote on a blockchain with tokens or shares. The record is mixed, from a $60 million hack in 2016 to a crowd that nearly bought a copy of the US Constitution.
Restaking lets crypto you have already staked earn a second time by securing other networks. It can pay more than plain staking, and it can cost more. Here is how staking, liquid staking and restaking actually differ, and where the risk really sits.
Ethereum's biggest layer 2 networks are rollups, and they come in two kinds. One assumes transactions are honest and checks later. The other proves every batch up front. Here is how optimistic and zero-knowledge rollups differ, and why the gap decides how fast you get your money out.
Self-custody means holding your own crypto keys instead of an exchange. It removes the risk of a platform failing, which no insurance covers, and hands you the full job of guarding the keys. Here is how it works and where it goes wrong.
A UTXO is an unspent piece of bitcoin your keys can spend. Bitcoin keeps no account balances, so your wallet adds up its UTXOs to show a total. Here is how the model works, why it sets your fee, and how it differs from Ethereum.
A token approval lets a smart contract move your coins, and a single bad one can empty a wallet. Here is what approvals are, how drainers abuse them, and how to revoke access before you lose anything.
Gas measures computational effort, not money. Since EIP-1559 the fee splits in two, and the larger part, the base fee, is burned out of existence rather than handed to a validator.
A blockchain is a shared ledger of transactions grouped into blocks, each one cryptographically linked to the block before it. NIST's own report deliberately dropped the word immutable, and the reason it did is the most useful thing to understand about how these systems work.
XRP is not a stablecoin. It is the free-floating cryptocurrency of the XRP Ledger, and its price moves with the market. The confusion comes from Ripple, the company tied to XRP, which launched a separate dollar stablecoin called RLUSD in December 2024.
Buying Bitcoin is legal for individuals across the UAE, and Dubai's VARA now licenses the platforms that sell it. This guide covers choosing a licensed exchange, passing identity checks, paying in dirhams, fees to watch, and keeping your coins safe.
