Cryptocurrencies are the future of global finance. They are the solution to many problems in the world. They can help stop the massive inflation that governments cause by printing too much money. It also has much more functionality with many use cases and Web3 Applications. You don't really have to understand any of that to make profits from it. Just buy Bitcoin and hold it for as many years as you can to see historically large returns. Try to buy when prices are low and wait for the next Bull Market in the near future to sell if you plan on taking profits.
Tier 1: Bitcoin: Bitcoin has been the #1 performing asset in the world over the past 10 years. Bitcoin is the gold standard of crypto and has become the replacement for physical gold as a flight-to-safety investment, as markets are volatile. Every 4 years, the amount of Bitcoin that miners produce is reduced by half. The maximum supply can never be more than 21 million, and many of the original Bitcoins that were mined have been lost forever, so the real maximum supply is closer to 15 million. As the supply drops and the demand increases, the price growth of Bitcoin will explode in the future.
As governments print more FIAT currency, the less it is worth and the more inflation robs their citizens of their buying power. Bitcoin and crypto are the cure for the FIAT problem. The more money and inflation that governments create, the more valuable Bitcoin will become. In the very near future, the SEC in the United States will approve Bitcoin ETFs, and the amount of global investment into Bitcoin will make the price skyrocket.
