Bitcoin is a record of data. That is all. But the properties of that record change everything.
What a blockchain is
Imagine a notebook that says how much bitcoin each person has. One page says I have 1 and you have 2. The next, that I have 1.5 and you 1.5, because you sent me half. That is the blockchain: the complete history of every transaction since day one.
To add a new page, the computers on the network compete to solve a very hard mathematical problem. The first to solve it adds the block and is paid in bitcoin as a reward. That is mining. There are computers doing this all over the world. There is no headquarters and no off switch: the network exists in all of them at once.
Why it has value
Bitcoin has a fixed maximum quantity, 21 million, not one more. Nobody can stop you making a transaction or take it from you without your key. Account freezes and bank-withdrawal limits exist because the banking system has a central point of control. Bitcoin does not.
The usual argument is that bitcoin is worthless because it has no backing. It fails at the root: value is subjective, there is no intrinsic value. People pay for software because it is useful, not because it is backed by gold. Bitcoin is the same: a good in itself, valued because its network has properties no government currency has.
The connection with Hayek
In 1976 Friedrich Hayek published Denationalisation of Money, arguing for an end to the state monopoly on currency and for letting private currencies compete: people would end up choosing the most stable ones, as medieval merchants chose coins of good alloy.
In October 2012 the European Central Bank itself, in its report Virtual Currency Schemes, wrote that the theoretical roots of Bitcoin lie in the Austrian school and its criticism of the fiat money system, and cited that book by Hayek. The institution that issues the euro was acknowledging where the alternative came from.
Beyond Bitcoin
Not all cryptocurrencies are the same. Bitcoin is the store of value: an asset to save in, with a fixed supply and hard to censor. There are other projects, such as the decentralised finance Ethereum built, contracts that execute themselves on the network with no intermediaries, and privacy coins such as Monero, where sender, recipient and amount are visible to nobody else.
That an asset exists does not make it an investment. Memecoins and speculative tokens with no use have no place in a serious course.
Why custody matters
Gold has a problem bitcoin does not: it is physical, and it can be confiscated. It has happened. On 5 April 1933 Roosevelt signed Executive Order 6102: Americans had to hand in their gold before 1 May, with penalties of up to ten years in prison. The ban on owning it lasted until 1974. A few recovery words you keep in your head cannot be confiscated.
What comes next
So far, the foundations: what wealth is, what money is, how the system that devalues your savings works and which real assets protect them.
Next comes the practical part: how to combine them in a portfolio, which countries and companies to choose, in what proportion for your situation and how to maintain it over time.
