I am not an expert on bitcoin, so please pardon me for dumb questions.
1, Will bitcoin not work any more in the far future? I think, not sure, every bitcoin transactions are recorded into memory or a block, and since this memory is so limited and hard to get, let's assure that your memory card is full or corrupted, then your expensive digital camera simply won't work anymore. So I think bitcoin owners pay too much on their memory card and forget about that the real value is in the camera.
2, What are the differences between a bitcoin and a memory block? I think they are the same thing, but on the other hand, I can spend a bitcoin, but I don't think I can spent a memory block.
3, I notice a payment that I sent days ago still haven't got confirmed. I sent 0.003 BTC and the fee I pick is 0.0003 BTC which was all I got in my wallet. That is too slow. I understand why, but I just can't accept it. So my third question will be what happen when everyone pick the same "priority" or Sat/b value, how long will it take for a transaction to go through in this unrealistic scenario?
4, It's basic economy, Supply and Demand. Since people are paying priority fee every new day, why would anyone want to process the lower fee transactions at all?
5, Is bitcoin really decentralized? but how can anything be decentralized when it's controlled by a group of people, namely those with a super computer. Well, it sorts of like the internet. Internet is controlled by few huge tech companies, some even controlled by its government.
