Haha I was just trying to figure that question out last week. And in all fairness, it is an abstract concept that took me a solid day to figure out. So here goes with what I coukd figure out about them bubzuru
Bitcoins are a currency that is transferred virtually anonymously through complex mathematical algorithms called blocks. These blocks are super complex, and must be solved in order to allow future transactions. Bitcoin mining is the act of using your GPU to solve these equations, for which you are rewarded 50 bitcoins. This is also how bitcoins are added to make the available currency pool larger. These bitcoin.generations are severly reatricted however due to a number of factors.
First, they are capped at 21 million. After 21 million bitcoins are generated there will be no more
Second, every week an algorithm runs and adjusts the complexity of the blocks so that bitcoins are geberated at roughly the same rate that gold is mined. At this point it takes about 2 weeks to solve a block and only the person who solved it gets the coins.
Also, I say virtually anonymous because anyone with no life can go back and look at blocks to trace transactions. However, it just aint worth their time cause of everything they would have to sort throufh. So it is possible, but 99% unlikely. Or thereabouts
So doing bitcoin mining on your own comp.just ain't worth the time tbh, however joining a bitcoin mining pool could be worth it. you'll have to check that out yourself. If I did a poor job explaining thia, ask for clarification and ill do what I can. Cahse I do think the hows and whys of bitcoins are quite confusing lol
