What is the difference between mining Monero and mining Litecoin?
The biggest difference is the hardware you compete against: Monero mining favors computer processors, while Litecoin mining is dominated by machines built specifically for mining. You can try Monero with a computer you already own, but competitive Litecoin mining usually means buying specialized equipment.
Your computer versus a dedicated mining machine
Mining means using computing power to help secure a cryptocurrency network. Miners compete to add a block—a batch of transactions—to its shared record and earn rewards.
Monero uses RandomX, a mining algorithm, or set of rules for that computing work. Introduced on November 30, 2019, RandomX favors CPUs, the general-purpose processors inside computers.
Litecoin uses Scrypt. Today, competitive Litecoin miners use Scrypt ASICs: application-specific integrated circuits. These are machines designed for a narrow task rather than everyday computing.
For you, that means:
- Monero: You can start with an existing CPU. Efficiency depends on its design, memory, and electricity use.
- Litecoin: An ordinary computer is not competitive with modern Scrypt ASICs. You need to consider equipment costs, cooling, noise, and electrical capacity.
Monero is designed to resist specialized-hardware dominance. That does not mean every CPU mines efficiently or profitably.
Memory matters differently
RandomX deliberately uses memory to make specialized mining hardware less attractive. Its fast mode uses a dataset of about 2,080 MB, plus working memory. Efficient mining generally needs about 2 MB of L3 cache per mining thread. L3 cache is fast memory inside your CPU; a thread is one stream of processing work.
RandomX also has a light mode with a 256 MB cache, but it is slower. More mining threads therefore do not always mean better performance.
Scrypt also uses memory, but specialized hardware manufacturers have successfully built ASICs for it. So “uses memory” does not automatically mean “good for mining on your computer.”
Browser-based Monero mining adds another limitation: browser security restrictions and processing overhead can make it much slower than dedicated mining software. Browser Litecoin mining is not a realistic competitor to Scrypt ASICs.
Rewards follow different schedules
Monero targets a block about every two minutes, and its mining difficulty adjusts every block. Difficulty controls how hard it is to find the next valid block.
Since around June 2022, Monero has had tail emission: a continuing reward of 0.6 XMR per block, plus transaction fees. That base reward is designed to continue indefinitely.
Litecoin targets a block about every 2.5 minutes. Its base reward halves every 840,000 blocks, roughly every four years, toward a maximum supply of 84 million LTC. Its difficulty adjusts every 2,016 blocks.
Litecoin also supports merged mining with Dogecoin. Participating miners can use the same Scrypt work to secure both networks without splitting their computing power between them. Your pool—a service where miners combine work and share rewards—determines how those earnings reach you.
Compare costs, not just mining speed
Do not compare Monero and Litecoin by their raw hash rates. A hash rate measures mining attempts per second, but RandomX and Scrypt perform different work.
Instead, compare:
- Equipment purchase cost and possible resale value.
- Electricity, cooling, and noise.
- Pool fees and payout rules.
- Estimated revenue using a live calculator.
Check whether a Litecoin calculator includes merged-mining income. For Monero, use your measured mining speed, especially if you mine in a browser. Neither option guarantees a profit.
The bottom line
Choose Monero if you want to experiment with CPU mining on your own computer. Consider Litecoin if you are prepared to operate specialized hardware and evaluate it as a larger equipment-and-electricity investment.
