I discover this guide while reading on how to start mining! How true is this?
The first step to mining Bitcoin at home is to build or purchase a mining rig. A mining rig is a computer specifically designed for mining cryptocurrencies. It will typically consist of multiple GPUs that are capable of performing complex mathematical calculations at high speeds.
Actually it wouldn't be profitable and efficient if you would try to mine Bitcoin with a GPU. Now we use ASICs. Only ASICs.
You can't mine BTC with GPU or CPU in 2023, not really possible.
Can I start with my smartphone?
No, you could mine some CPU coins with your smartphone, and swap these coins to BTC. But you wouldn't be profitable, and you will probably quickly kill your smartphone.
The only way you can use your smartphone to start mining cryptocurrency is through a mining app. These mining apps put you in mining pools, i.e. groups of other miners, that utilize the hardware present inside your smartphone to mine cryptocurrency at a specific hashrate.
If you know much better please what is missing here, so we can learn?
Yeah mining pools are a thing lol, a Google search will tell you everything you need to know about it.
Forget the idea to mine BTC with a smartphone. if people are buying ASICs and paying big amounts of money for electricity, it is not for nothing.
You should spend some time here to learn about ASIC, Bitcoin mining basics stuff like pools, payments shemas etc..etc...
Everything you wlll need to learn is already here, we are not going to explain them thousands of time, just some researches in the Mining section of the forum will help you in the same way
Happy hashing if you start to mine in the future!
