Suppose that someone invented a crypto postal service. Or is short a crypto-post. Its purpose is to transfer envelopes and boxes quickly, safely, and decentrally. However, there is a catch. The envelopes and boxes are empty. They hold nothing. From the outside, the crypto-post would look similar to a traditional post. Because obviously, a traditional post transfers envelopes and boxes. And that crypto-post transfers them as well. But in reality, it would be the dumbest thing ever invented given that people need letters, documents and products, not envelopes and boxes. The latter only serves as a container to hold the former.
The so-called crypto-currencies, such as Bitcoin, are exactly like our hypothetical crypto-post. From the outside, Bitcoin looks similar to traditional currencies. It is a system that has units transferred between people. If you have a bank account or a banknote, what you have is some name such as USD, EUR, or GBP, and a number that represents the quantity of units in a banking system. If you have a Bitcoin account you also have a name - BTC and a number that represents the quantity of units in the Bitcoin system. But the catch is that the units in the Bitcoin system are empty. They are like envelopes and boxes in our crypto-post. They are containers that hold nothing.
On the other hand, units of traditional currencies are containers that hold a debt-based asset. Namely, these units are created by commercial banks issuing loans or by central banks purchasing government bonds. So if you have for example dollars, you have a resource that the US government and masses of individuals and companies need for satisfying debt owed to the US banking system. If your neighbor has a $500K loan with a mortgage on his house, while you have $500K, you have something they need to get rid of the mortgage. Just like people need food to get rid of hunger. When you have an item that can satisfy people's needs, you have a valuable resource, you have an asset.
Given that units in the Bitcoin system are not created by issuing loans or purchasing bonds, they don't hold a debt-based asset. They neither hold some tangible asset like a precious metal or food nor some intangible asset like a patent, copyright, or license. Also, they don't hold equity of some company, like shares. Simply put, in the Bitcoin system, people have empty units, units that hold no asset. Consequently, there's nothing to assign value to.
Often, people would say that Bitcoin is simple and thus better than a complex banking system that manages fiat currencies. But of course Bitcoin is simple given that it manages empty units. Fiat currency units hold a debt-based asset and managing debt is complex. It includes credit assessments, contracts, collaterals, foreclosures, etc. Implementing those requires both people and infrastructure. In the case of Bitcoin, however, the author just wrote a protocol that tells people: "You have 10 units", "you have 0.5 units", "you have 50 units", etc. It is literally like giving people play money for kids or Monopoly money - they get 'monetary units' for trading purposes but these units hold no asset. They are empty. People currently pay $70K for such a unit. Also, managing these units requires the consumption of enormous amounts of electricity - 141-160 terawatt-hours annually according to some estimates. Imagine the absurdity of giving up 70 thousand asset-holding units only to get 1 Monopoly-money-like unit. Or the absurdity where a postal service spends as much electricity as the entire country of Norway only to transfer empty envelopes and boxes. That's why Bitcoin is the dumbest thing ever invented.
I'm sorry. If you have this idea about Bitcoin then people like you don't need Bitcoin. Why do you make bad comments about bitcoin without knowing about bitcoin. Because where people are constantly dependent on Bitcoin, your comments are completely absurd. If you don't like investing in Bitcoin, I understand you have no idea about Bitcoin. Because people are making quite good money investing in Bitcoin. If you want to invest in Bitcoin, you must invest with a long-term plan. And if you don't want of course you can invest any.
