How is a new cryptocurrency created?

A new cryptocurrency is created in one of two ways: by launching a new blockchain with its own coin, or by issuing a token on a blockchain that already exists. The second route is far easier and accounts for the great majority of cryptocurrencies. Making one takes little skill. Making one that holds value is the hard part.

How is a new blockchain launched?

A coin is the built-in asset of its own blockchain, as bitcoin and ether are. To create one, a team writes the network's software or copies and adapts the open-source code of an existing network. Litecoin and Dogecoin both began as modified versions of bitcoin's code.

Code is not enough. A blockchain needs independent operators to process transactions and keep copies of the record. Without them it is slow, easy to attack, or controlled in practice by its founders. Attracting those operators takes time and usually money.

How is a token issued on an existing chain?

A token is an asset that lives on someone else's blockchain. It is created by a smart contract, a small program stored on the chain that keeps a list of who holds how many units. The guide to coins and tokens explains the distinction.

Networks such as Ethereum and Solana publish standard templates for tokens. The creator chooses a name, a ticker symbol and a supply, then pays a network fee to publish the contract. Some websites reduce the process to filling in a form. That is how most meme coins are made, and it is why new tokens appear in large numbers.

Who can create one, and is it legal?

Anyone with an internet connection can. Publishing code on a public blockchain requires no license or approval.

What the creator does next is another matter. Selling a token to the public as an investment can fall under securities law, as many projects found after the 2017 boom in initial coin offerings. Businesses that handle customers' money face anti-money-laundering rules, and false promises to buyers can amount to fraud. Rules differ by country and state, and they change, so the official source or a qualified professional is the place to check.

Why is creating one easy but value hard?

A token is worth something only if people want to hold or use it. That takes more than code:

• a use, such as paying fees or accessing a service
• a market where it can be bought and sold without moving the price too far
• confidence that the creators cannot print more or drain the funds

The rules that govern a token's supply and distribution are called tokenomics. They often show who benefits. If insiders hold most of the supply, they can sell into any rise.

Most new tokens soon lose their buyers. Some are built to enrich their creators at buyers' expense, a scheme known as a rug pull.
