3 Reasons You Shouldn’t Use a Laptop for Crypto Mining


We all have different opinions regarding cryptocurrency mining. Some love it, while others don’t. But there are some things most of us can agree on. One of them is the fact that mining crypto on a laptop is a terrible idea.

The act of mining cryptocurrency is best left to desktop computers or specially designed mining rigs. Here, we will discuss exactly why you should never buy or use a laptop for mining.

1. Mining on a laptop is not profitable

First of all, one of the main obstacles to mining on laptops stems from the simple fact that laptop GPUs are often weaker and more expensive than their desktop variants. There’s a reason you can get a gaming laptop without a hitch while most GPUs seem to be dead these days: miners aren’t looking for laptops, and there’s a reason for that.

Sure, we have Ampere and RDNA 2 GPUs available for laptops, and they’re fantastic for gaming. But when it comes to actual power, a laptop Nvidia GeForce RTX 3080 Ti is about as fast as a desktop RTX 3060 Ti in both benchmarks and proper mining performance (hash rate).

This poses a problem in that it will take several months to even see anything close to a return on investment in most cases. A laptop equipped with a RTX 3080Ti it will cost you around $3,000-$3,500. If you mine as well as an RTX 3070, you can expect to earn $2 per day, $60 per month, or $720 per year depending on the difficulty of the Ethereum network at the time of writing.

It will take five years to recover the money from your investment. That’s with good thermal temps, which you don’t – your laptop probably doesn’t have enough cooling capacity to remove heat efficiently, and your computer will be constantly thermal throttling to keep up. And we haven’t even factored in electricity – add in the electricity costs of owning a laptop with a charger that draws power from your wall 24/7, and your profits dwindle even further.

You are better off spending the money on a proper mining rig or just a desktop. GPUs are still hard to come by, but if you go mine, it’s probably even better to buy GPUs from resellers than use a gaming laptop.

2. Laptops are not made for mining

Then we have the fact that laptops are not intended for mining and therefore should not be used for it. And this isn’t just a manufacturer recommendation, but the way laptops are designed makes it a horrible idea.

First, let’s see why desktop GPUs can generally mine cryptocurrencies:

Desktop computers, especially mid-tower and full-tower ones, have plenty of room inside for components to breathe. And that space is essential. cryptocurrency mining is a computationally intense activity which can activate your entire GPU, crunching numbers to verify transactions and generating a lot of heat in the process.

Desktop GPUs are equipped with active cooling (fans or water cooling) that can help them dissipate the heat they emit. And the computer case has plenty of internal space and robust intake/exhaust fans to help heat escape from the computer.

Laptops do too. But they are not equipped to handle the kind of heat that mining would generate.

Laptops, even gaming ones, have a much slimmer profile and much smaller interior space. The fans that are fitted inside are also much smaller and weaker. They’re enough to handle daily operations, and gaming laptops can even tackle some games without breaking a sweat. But mining is a much more strenuous activity. You should be aware of the fact that mining is usually a 24/7 process, and you are putting a lot of unnecessary stress on your laptop.

Not only can it damage your GPU in the long run, but it can also wear out the tiny fans, which can further complicate things. Also, your device’s battery doesn’t like heat either. And if your laptop gets really hot, the battery can drain too. It’s a messy chain of events that can cause your laptop to die much sooner than it would otherwise.

3. The e-waste dilemma

We already established that having your laptop mine crypto can help you find an early demise, but what happens once it dies? Depending on what you’ve fried, you might be able to revive it, but most laptops used for mining usually only have one destination: a landfill, where it becomes e-waste.

Once a GPU is ruined due to mining, in most cases, it cannot be brought back to life, which means it has to be thrown away. The average lifespan of a mining GPU is about half of what it would last in typical use, and that’s with proper thermals. The same goes for laptops: if you fry the GPU, depending on the model, it may be repairable, but in most cases, it’s dead and will be part of the growing e-waste stats.

It can also damage other components, and these can have different levels of severity, from repairable to outright dead. However, this means that everything ends up in a landfill sooner than it should.

Please don’t mine on your laptop

The moral of the story is that you should not mine on your laptop under any circumstances. You have a good chance of damaging it, or at least reducing its lifespan, while also not making too much money.

You’ll be much better off mining through other means. You can build a desktop PC with ample cooling if you want to use just one GPU for some passive gains. You can also set up a suitable mining rig if you plan to mine Ethereum or buy an ASIC miner if you prefer to mine Bitcoin.
