What Is a Memecoin?

In December 2013 two software engineers, Billy Markus and Jackson Palmer, stuck a Shiba Inu meme on a coin to take the mickey out of crypto speculation. New coins were launching weekly back then, most pitched as the next bitcoin, and Dogecoin existed to laugh at the lot of them. The joke stuck. It has outlived thousands of the serious projects it was mocking.

That is the founding story of the memecoin: a coin whose product is attention. This guide describes how that market works, with names and dates attached. It does not recommend any coin, and it is not financial advice.

A coin whose product is attention

Most crypto projects claim to be building something: a payments rail, a lending market, a faster chain. A memecoin claims a joke and a community, and usually says so out loud. There is no revenue to model, no roadmap to fall behind and no product to ship late, so the price runs on attention, multiplied by community, multiplied by liquidity.

An altcoin with a roadmap can at least be measured against its own promises. A memecoin makes almost none, which is strangely honest as marketing goes.

Attention is even measurable, crudely, because holder counts, posting volume and trade flow are all public, all fast-moving, and the nearest thing this market has to fundamentals.

Dogecoin demonstrated the mechanism long after both founders had moved on. In early 2021 a run of tweets set off vertical price surges in a coin that had not shipped anything new: the attention arrived, the price followed.

From one joke to a feed of them

For years, copying the joke took real work: code, a token contract, an exchange willing to list you, and a story worth retelling once the novelty wore off. Shiba Inu, a token on Ethereum, managed all four, led the dog-coin wave of 2020 and 2021, and pulled hundreds of dog-themed imitators into existence behind it.

Then the work disappeared: pump.fun, launched on Solana in January 2024, made creating a token a one-click job costing next to nothing, and millions of tokens followed. Creation stopped being an event and became a feed.

A launch now looks like a social post: picture, ticker, a small pool of money, live within a minute. Most collect a handful of trades and fade the same week.

The venue was no accident: Solana's fees are tiny, so the 2024 to 2025 memecoin wave ran mostly there. Cheap transactions make small speculative trades viable, and that is the entire reason.

Why the moves are so violent

Memecoin markets are shallow: order books and liquidity pools often hold very little on either side, so a modest buy can double a price and one determined seller can halve it. The violence runs in both directions, and it comes from thin depth, not from anything the project did or said.

Order matters in a thin pool too: the first sellers get the quoted price, and later ones get whatever depth is left.

Attention behaves the same way: it spikes off one platform, then decays as the feed moves on. Of the millions of tokens minted through one-click factories, most now sit at approximately zero. Not hacked, not stolen, just abandoned.

The failure modes, with receipts

The classic exit is the rug pull: creators keep a large slice of the supply, wait for buyers, then dump it. Or they pull the liquidity out of the trading pool, and after that nobody can sell at any price.

The nastier variant is the honeypot: a token coded so you can buy but never sell. The canonical case is SQUID, a November 2021 token themed on the Squid Game series. Its price climbed while buyers discovered, one at a time, that sell orders went nowhere, and when it finally collapsed to effectively nothing the one-way traffic had been sitting on the chain in plain view the whole time.

Concentration is the quieter risk: when a few wallets hold most of the supply, those wallets control everyone's exit. And celebrity promotions recur every cycle: a famous name posts, the token spikes, early wallets sell into the crowd. In October 2022 Kim Kardashian paid $1.26 million to settle US SEC charges over an undisclosed paid promotion of a token called EthereumMax.

Every one of these leaves some trace in public view, usually before anything goes wrong.

Gambling-adjacent, and everyone in it knows

Memecoins are attention markets sitting somewhere next to gambling, many of the people trading them would say exactly that without blinking, and plenty treat the whole thing as entertainment with a stake attached. The coins that persist, Dogecoin above all, are the rare exceptions people remember. Survivorship does the rest of the marketing.

What anyone can verify

None of this needs insider access: every balance, every trade and every pool sits on a public chain, and a block explorer reads it all for free, no account needed. Solscan reads Solana, Etherscan reads Ethereum. The habit transfers too: the same explorer that shows a memecoin's holder list will track any transfer you ever make.

Three things sit on the record at all times. Supply concentration: the holders tab shows whether the top few wallets own most of the coin, which is the raw material of a rug pull. Liquidity depth: how much money actually sits in the pool, which decides whether an exit exists at all. And live sales: recent transactions show whether holders are managing to sell, the exact check SQUID buyers never made.

But what the crowd chases next is recorded nowhere. Attention is the one input you cannot look up.
