Altcoins, from the ground up.

What is an altcoin?

Altcoin is a broad term for a cryptocurrency other than Bitcoin. It covers very different systems: native coins that help operate a blockchain, tokens used inside applications, governance assets, and assets designed to track another unit of value. The label describes a relationship to Bitcoin; it does not tell you whether a project is useful, secure, or suitable for your circumstances.

Begin with the beginner’s guide to altcoins, then look at the asset’s own documentation. Ask what a holder actually controls, where balances are recorded, and whether the asset gives any enforceable rights. A project’s popularity cannot answer those questions.

Separate the coin from the network

A network is the system that records and validates activity. Its native asset often pays transaction fees or has a role in network security. A token is usually created through an application or program on an existing network. The same ticker can appear on several chains, and matching names do not prove that two tokens are interchangeable.

Our coins versus tokens comparison explains the distinction. When identifying a token, check its network and contract or mint address through the project’s official channels. When transferring it, confirm that the receiving service supports that exact network and asset.

A useful research order

1. Purpose: Describe the problem the project addresses in one clear sentence. Identify who would use it and why the token is needed.
2. Control: Check who can upgrade contracts, mint additional supply, pause transfers, or spend a treasury.
3. Supply: Examine circulating supply, future issuance, allocation, and unlock schedules. A low unit price is not a measure of cheapness.
4. Use: Distinguish repeat activity from incentives, promotional campaigns, and temporary speculation.
5. Exit: Consider available liquidity, withdrawal conditions, network costs, and the consequences of a market disruption.

Use the altcoin research walkthrough to turn these questions into a repeatable process. Record what you can verify and what remains uncertain. The outcome of good research can be a decision to wait or avoid an asset.

Match the question to the guide

Build a view of the risks

Price movements are only one part of the picture. An asset can remain tradable while its application loses users; a functioning project can still have a falling token price. Custody failure, compromised permissions, and unavailable withdrawals can matter before a price chart changes.

Read the security guide alongside project research. Keep operational questions separate from expectations about price, and revisit your assumptions whenever a project’s design or access conditions change.

Technical starting point: Ethereum’s ERC-20 documentation explains a widely used token interface. A technical standard describes behavior; it is not an endorsement of assets built with it.
