Yes. The main thing that matters with miners is the hashpower - how many hashes it can do per second.
If you get stronger miner it can do more hashes per second, but also if you get 2 miners (they look like desktop computers without a monitor), then you will earn twice as much Bitcoin. The miners consume electricity, so you need to think about your electricity bill...
Thank you for the quick and understandable answer! A follow up:
What prevents a state buying the largest farm and make sure it gets all the new goodies from now in?
Generally it's hard to manufacture a lot more miners, you need big factories, etc. But overall nothing prevents states from mining and they should start mining (El Salvador does for example).
Miners don't have that many powers over the network, so even if states mine, it just makes Bitcoin stronger.
Doesn’t a state that mines gets all the mined bitcoins? How can I compete with a single computer with a power of mining state?
In other words, why does El Salvador does not get all the mined bitcoins in the world?
No, the newly mined bitcoins get assigned based on your hashpower. If you have more hashpower, then you get more bitcoins, if you have less hashpower you get less bitcoins. But even a small player can still get some bitcoins. As I mentioned you also need to pay for more electricity if you have more miners.
Now, when you are only an individual person that has one or two mining boxes, the way that Bitcoin works you would actually get some Bitcoin only really rarely (e.g. once in 2 years if you are lucky) and so that's why people join "mining pools" where you have somewhat guaranteed steady payouts of the bitcoin based on the hashpower you contribute to the pool.
It's quite interesting how this is actually done technically, I'm happy to explain that, but it's a bit more complicated.
Cool! So practically, a state can mine bitcoin but it may be not cost efficient and little plebs like me could still get a piece of the reward pie but much less frequently.
Hashrate is the power of all miners combined so states becomes smaller and smaller entities in the overall pools
Also, halvings probably will increase the cost of bitcoin due to the need to consume same or bigger amount of energy to accumulate half of the botcoins
Did I understand correctly?
