Bitcoin is not magic, and its price is volatile. But it was built to answer concrete problems. Here are four.
1. Money that slowly loses value
The ECB aims for 2% inflation a year, the view being that mild inflation is good for the economy. The cost: at 2%, a euro buys half as much after about 35 years. Savers have to invest just to keep up.
Bitcoin's answer: a fixed supply of under 21 million coins, issued on a public schedule no one can change alone.
2. Billions without a bank
The World Bank's Global Findex 2025 found 79% of adults have an account, so roughly one in five do not.
Bitcoin's answer: anyone with a phone can create a wallet. No application, no permission.
3. Expensive transfers home
Sending $200 abroad cost on average 6.36% in Q3 2025, and about 15% through banks. The UN target is 3%.
Bitcoin's answer: peer-to-peer payments, and on the Lightning Network, fees that are often a tiny fraction of a cent. (Converting to and from local currency still costs something.)
4. Trusting middlemen
Banks can freeze accounts, and failed firms can lose customer money: FTX's founder was sentenced to 25 years after misusing over $8 billion of customer funds.
Bitcoin's answer: with self-custody, only your keys can move your coins. No one can freeze or lend them out.
Takeaway
Bitcoin trades some convenience and price stability for scarcity, openness and control. Whether that trade suits you is your decision; the problems it targets are real.
