Therefore, expanding the block is like increasing the Bitcoin limit of 21 million, and segwit removing the signature data is like buying half of the goods.
I don't understand how you made that assumption. The coins will always be 21 million. Who said that segwit removed the signature data? How's that possible and how is it related with buying half of the goods?
I can understand that the user pays transaction fees to buy the bytes of the block, so the byte of the block is a commodity, and the quantity of this commodity is fixed. The demand comes from the fact that the trader needs this byte to confirm the transaction.
So you're saying that only traders need this "byte" to confirm the transaction? The others don't?
This is to fundamentally change Bitcoin and reconsolidate the decentralized rights into the hands of a few people. Segwit is increasing the rights of miners, and expanding blocks is to issue more commodities to miners, just like the right to print money for miners.
Why segwit increases the rights of miners? It reduces the fee of the payer. Miners "print" money from the block reward, not from the transactions' fees. I guess this is what you meant.
These are not the way of Bitcoin. The transaction volume is a pseudo-demand. This is not a real problem. The real function of money is not to pay the bills. The function of money is to store value.
This is clearly a subjective perspective. You can either spend your money and "let the dollar circulate", as would happen on a healthy capitalism, or keep them on your closet as a store of value. Although, last time I checked, store of value assets don't tend to inflate.
It is naive to imagine Bitcoin to buy coffee, but people can use Bitcoin to buy coffee consumption cards or coffee points. This is okay, and there is no problem of privacy leakage.
The "buying-coffee-with-bitcoin" dream has been forgotten years now. Especially to a coffee shop you've never entered before. The payee must ensure that you'll not double spend, so you'll have to wait for a confirmation. Even if you'd paid $50 as a fee, which would have very high priority right now, you'd still have to wait for 5-10 minutes on average to be confirmed. The lightning network, on the other hand can only work if you buy from that coffee shop everyday and close the channel at the end of the month (for example).
Now that there are bitcoin core and bitcoin cash, they can’t be said to be the original bitcoin, they are modified versions of bitcoin.
First of all, Bitcoin Core is Bitcoin's
client. The way you've written it, is like it's another fork. Secondly, you're naming Bitcoin Core and Bitcoin Cash "modified versions of bitcoin". This is false. Bitcoin
Core is being developed from the Bitcoin Developers. Those who were chosen after Satoshi Nakamoto, the person(s) that began the so-called "Original Bitcoin". On the other hand, on Bitcoin Cash, some other developers decided that they don't like the way Bitcoin works and started a new chain in which its units
aren't bitcoins.
As for how Bitcoin disappeared, the reason is the price. The huge price increase created the illusion of success of Bitcoin. But, when Bitcoin and price are closely linked, Bitcoin cannot be used. This price increase is traditional currency issuer attack, no one noticed
The price of commodity on a completely free market, where the only rule is demand and supply is its value that has been given to it by the majority of those who sell it. This is my opinion. I'll agree with you that it can't look as a currency this way.
Investors continue to change Bitcoin, making Bitcoin a perfect story, but it is only a story. Investors say that they want to replace Visa, but they don’t say why they want to replace Visa. It’s just a valuation of Bitcoin based on Visa.
Investors don't change bitcoin. They try to make profit from it since it's a free market competition which means that it fluctuates a lot. There are people who invest in fiat too, but its price doesn't get affected that much, because
it's not a free market competition. As for the investors' influence to other people: It has nothing to do with Bitcoin's "disappearance".
So, Bitcoin will not become money, so how can you buy coffee? In order to allow Bitcoin to buy coffee and change Bitcoin into an investment product, is this a huge joke?
I already told you about the "coffee" dream. I want you, though, to notice something. Once you make a transaction it gets broadcasted to all these thousands of nodes. All these computers will save on their disk that you sent some satoshis to someone else and that you want it to be confirmed fast. How can this be cheap? I mentioned this, because that was the idea of bitcoin pre-segwit. When it "was" "still" "original". You'd have to understand that it'd be a matter of time before transaction cost became higher even if we're still on v0.1 with satoshi being active everyday.
The developer completely isolates the technology from the user, and the user does not know what address, private key, public key, and signature are. These things should be extremely simple, so that all users understand what is protecting Bitcoin, not a dozen words Protecting the funds they have worked so hard to get.
If the user doesn't know about it, then he/she ought to learn! Except if he/she does not care about the funds' protection that much. Some things in life aren't simple, those are usually the most interesting.
Anyone who says that ordinary people cannot understand Bitcoin is wrong.
So you're saying that you're wrong?
