Crypto

A cryptocurrency is a digital asset that uses cryptography to secure transactions, control the creation of new units, and verify transfers — without requiring a central authority such as a bank, government, or payment processor to operate.

Before blockchain, digital record-keeping required a trusted central authority: a bank holds your balance, a company holds your data, a government maintains the register. Centralised records are efficient but create single points of failure — they can be hacked, corrupted, or manipulated by…

Bitcoin was the first cryptocurrency and remains the largest by market capitalisation. But the ecosystem that grew from Nakamoto's whitepaper has expanded into thousands of distinct digital assets, each with different technical architectures, use cases, and investment profiles. Understanding the…

Bitcoin has a hard cap of 21 million coins. This limit is not a policy decision that can be changed by a vote or executive order — it is written into Bitcoin's protocol and enforced by every node on the network. Any attempt to increase the supply would be rejected by the existing network and would…

One of the most persistent Bitcoin investment theses is that it is, or will become, a digital analogue to gold — a store of value that preserves purchasing power over time, independent of any government or central bank. Proponents argue that Bitcoin improves upon gold in several key dimensions…

Bitcoin's price history is characterised by extreme volatility structured around recurring market cycles: multi-year periods of explosive appreciation followed by prolonged and severe drawdowns. These cycles have roughly corresponded with the Bitcoin halving schedule — occurring approximately…

Ethereum was proposed by Vitalik Buterin in a 2013 whitepaper and launched in July 2015. Its defining innovation was the smart contract: self-executing code stored on the blockchain that runs automatically when predefined conditions are met, without requiring a trusted intermediary to enforce the…

Beyond Bitcoin and Ethereum, the cryptocurrency market contains thousands of alternative coins — "altcoins" — with a combined market capitalisation that can represent anywhere from 20% to 60% of the total crypto market depending on market conditions. Understanding this landscape requires…

In the crypto ecosystem, a useful distinction exists between coins and tokens. Coins are the native currencies of their own blockchain (Bitcoin on the Bitcoin network, Ether on Ethereum). Tokens are assets created on top of an existing blockchain using smart contracts.

One of the most debated questions about cryptocurrency as a portfolio asset is whether it provides genuine diversification — a low or negative correlation with traditional asset classes, particularly equities — or whether it simply adds volatility without the uncorrelated return benefit that makes…

Portfolio allocation to cryptocurrency requires confronting its fundamental characteristics honestly: extraordinary volatility, unproven long-term value storage, uncertain regulatory environment, and potential for total loss — alongside genuine potential for very large returns if the technology…

In traditional finance, your assets are held by custodians (banks, brokerages) whose insolvency is partially protected by regulatory schemes (FSCS in the UK, SIPC in the US). In crypto, asset security depends entirely on who holds the private keys — the cryptographic credentials that authorise…
