Bill Gates stated that cryptocurrencies are "100% based on the greater fool theory." This theory is an idea from the financial world that suggests it is possible to make money with overvalued assets — such as real estate, stocks, or cryptocurrencies — as long as there is always someone willing to pay more for them, that is, a "greater fool."
The problem is that people who earn salaries cannot make investments that yield profits in these overvalued assets like eBay, Amazon, Google, among others, which only fatten their fortunes and the dividends are very low. If one had bought shares of Google in the 90s, then yes, it would have yielded profit; over the years in this case, it would have only yielded results above $50,000 and it is not for everyone, it is a matter of doing the math.
The idea of a decentralized system has been around since the 80s, where the idea would be that banks, large companies, and governments could control our investments and savings. This is not being foolish; the problem is that taxes and fees are very high and are constantly charged in the centralized system, and these individuals are the ones who control the governments and elected them. Do not be deceived; in any case, we will pay taxes when withdrawing our money from the brokers out here, but only at the right moment. If we observe nowadays, we have been using digital money for a long time through credit and debit cards; we are just shifting the money from one place to another, from banks to a blockchain; it is necessary to understand this.
Conclusion. This only changes things around; in my view, it is not foolish at all, it is technological evolution, $BTC $PEPE $SHIB
