FSO NEWS: What Is Litecoin? The 15-Year-Old 'Silver to Bitcoin's Gold' Explained

What Is Litecoin? LTC, launched October 2011, with an 84 million coin cap

Key takeaways

Litecoin was launched in October 2011 by former Google engineer Charlie Lee as a lighter, faster version of bitcoin.
It produces a block every 2.5 minutes, uses the Scrypt mining algorithm and has a hard cap of 84 million coins.
Litecoin often tests upgrades before bitcoin does, and it added an optional privacy feature called MWEB in 2022.
In 2026, a bug in that privacy feature was exploited. Miners contained it, the code was fixed, and the project says no user losses were confirmed.
A U.S. spot Litecoin ETF has traded since October 2025. LTC was about $61.35 on October 21, 2026, according to TokenPost.

Litecoin is one of the oldest cryptocurrencies still in wide use. For years it was described as the "silver to bitcoin's gold": a similar design, built for cheaper and quicker everyday payments. Fifteen years after its launch, it still runs on much of the same core code as bitcoin, and it is still mined, traded and used for payments around the world.

This guide explains how Litecoin began, how it works, where it is used, what happened in 2026 and what risks remain. If you want the backstory of the coin Litecoin was copied from, start with our piece on the origins of bitcoin.

Origins: Charlie Lee's "lite" bitcoin

Charlie Lee, then a software engineer at Google, released Litecoin on October 7, 2011. He took bitcoin's open-source code and changed a few key settings. Blocks would come four times as often, the total supply would be four times as large, and mining would use a different algorithm that, at the time, was harder to dominate with specialized hardware.

Lee later joined Coinbase as director of engineering, then left in 2017 to work on Litecoin full-time through the nonprofit Litecoin Foundation.

In December 2017, near the peak of that year's crypto boom, Lee said he had sold or donated almost all of his LTC. He told CNBC that owning the coin while tweeting about it created a conflict of interest.

How Litecoin works

Proof of work with Scrypt

Like bitcoin, Litecoin is secured by miners who compete to add each new block and earn newly issued LTC plus fees. Litecoin uses the Scrypt algorithm rather than bitcoin's SHA-256. Specialized Scrypt mining machines arrived years ago, so Litecoin is no longer mined on home computers.

Litecoin is also merge-mined with Dogecoin. Miners can secure both networks with the same work, which adds to the security of each.

Faster blocks and a fixed supply

A new Litecoin block arrives about every 2.5 minutes, compared with about 10 minutes for bitcoin. The supply is capped at 84 million LTC.

Like bitcoin, Litecoin cuts its mining reward in half every 840,000 blocks, roughly every four years. The most recent halving, in August 2023, cut the reward from 12.5 to 6.25 LTC per block. The next one, at block 3,360,000, will cut it to 3.125 LTC. Tracking sites currently estimate that for mid-2027, but the exact date depends on how quickly blocks are found.

MWEB: optional privacy

In May 2022, Litecoin activated MimbleWimble Extension Blocks (MWEB). It lets users move coins into a separate, optional layer where amounts are hidden, then move them back out. Normal Litecoin transactions remain public, as on bitcoin.

What Litecoin is used for

Payments. Low fees and quick confirmations make LTC popular with payment processors and merchants that accept crypto. PayPal added Litecoin when it opened crypto trading to U.S. users in late 2020.
A testing ground. Litecoin adopted Segregated Witness (SegWit), an important bitcoin upgrade, in 2017 before bitcoin did, and it was an early home for Lightning Network payment experiments.
Long-term holding. Some investors treat LTC as a smaller, cheaper alternative to bitcoin with a similar fixed-supply design.

Key milestones

October 7, 2011: Litecoin launches.
May 2017: SegWit activates on Litecoin.
December 2017: Lee says he has sold or donated nearly all his LTC.
October 2020: PayPal adds Litecoin alongside bitcoin, Ethereum and Bitcoin Cash.
September 13, 2021: A fake press release claiming Walmart would accept Litecoin briefly sends the price soaring. Walmart said the release was not authentic.
May 2022: MWEB privacy upgrade activates.
August 2023: The third halving cuts block rewards to 6.25 LTC.
October 28, 2025: The Canary Litecoin ETF (LTCC) begins trading on Nasdaq, the first U.S. spot Litecoin ETF.

Litecoin's strength is its long, mostly steady track record. Its challenge is standing out when bitcoin, stablecoins and faster networks all compete for the same payments.

Recent developments in 2026

The MWEB bug

According to a postmortem published by Litecoin developer David Burkett on April 28, 2026, someone exploited a critical validation bug in MWEB in March 2026 at block 3,073,882. It let them create an invalid withdrawal of 85,034.47 LTC from the privacy layer.

Miners froze the affected coins. The person behind it returned the funds in exchange for an 850 LTC bounty, which Lee personally covered. A second attempt on April 25 created a short invalid chain of 13 blocks that was then reversed. Two outside services that accepted those transactions lost money: NEAR Intents, on a swap of about 11,000 LTC, and THORChain, which lost about 10 LTC. The bug was fixed in Litecoin Core 0.21.5.4, and the postmortem reports no confirmed losses for regular users.

Other news

Commodity status. In March 2026, the SEC, joined by the CFTC, named Litecoin among its examples of "digital commodities," not securities.
More ETFs. On September 11, 2026, Grayscale filed an amended registration to convert its Litecoin Trust into an ETF on NYSE Arca under the ticker LTCN. That conversion still needs regulatory sign-off.
LitVM. On October 27, 2026, the LitVM team announced V2 of its Ethereum-compatible layer for Litecoin, designed to bring apps such as lending to LTC. Parts of the upgrade are still being rolled out.

Risks to consider

Price swings. LTC traded around $61.35 on October 21, 2026, per TokenPost, far below its 2021 highs. Like most crypto, it can fall quickly. See our explainer on understanding volatility.
Competition. Stablecoins now handle much of crypto's payment activity, and bitcoin's own payment tools have improved.
Software risk. The 2026 MWEB bug showed that even mature, battle-tested code can have serious flaws, especially in newer features.
Exchange and custody risk. Coins on an exchange are only as safe as the exchange. Chainalysis estimated about $6.4 billion was stolen from Binance in October 2026, the largest crypto theft on record.

The bottom line

Litecoin is a veteran of crypto: simple, predictable, capped at 84 million coins and running for 15 years. It now has ETF access in the U.S. and clear commodity treatment from regulators. But it has lost ground to newer networks and stablecoins, and the 2026 MWEB bug was a reminder that no code is risk-free. It may suit investors who want a smaller, bitcoin-like asset, but it should be sized as a speculative holding.
