Can we profit from mining now and with the LHR version?

In conclusion, it is possible to make a profit if you use a high performance graphics card.
However, your earnings will increase or decrease depending on the price fluctuations of bitcoin. If the value of bitcoin continues to decline, it may become difficult to monetize. The situation changes daily.
In addition, it takes a certain amount of time to recover the upfront investment made to start mining, so it is suitable for people who can wait patiently.

Please refer to this as an example only.

The LHR version is a graphics card with a “Lite Hash Rate”, which means that the mining performance is limited to about 50%, but the limitation is only for Ethereum mining, not for other types of mining.
As of November 2021, I tried for a week to see if I could mine in my free time on a computer used for rendering 3D images (one GeForce RTX 3070 Ti LHR graphics card), and the results showed that I was paid about $3.4 a day, with an electricity bill of about $1.7. The reward is paid in bitcoins, so I am currently mining with 4 graphics cards, hoping that the crypto assets will increase further.

Configuration of a mining rig

In this day and age, the high price of graphics cards is unavoidable.
But I want to make the initial investment as cheap as possible.
I searched for the cheapest prices on Rakuten and Amazon, and used auctions to get the equipment I needed for my mining rig.
The whole thing cost me about $3500, though…

So what’s the actual profit?

One week has passed since I started operating the mining rig.
As of November 22, I’m getting about $5 a day and my electricity bill is about 200 yen, so my profit is about $3.5 a day.
So, it will take me two years to recover my investment.
But I’m planning to add another graphics card, so we’ll see how that changes things.

Note: As of February 2022, I am running with four graphics cards.

see you later!
