Cryptocurrencies can have a broad range of uses depending on what you want to get out of them and the type of cryptocurrency you’re using
They all have different use cases. Some are better than others.
Speculation
People like to buy and sell cryptocurrencies because they could possibly be worth more in the future. Often financial gain is the strongest reason people get into crypto.
A store of wealth
The largest cryptocurrency Bitcoin is widely held by people who want to fight inflation (prices going up), want to preserve their purchasing power or believe some cryptocurrencies offer a better alternative in a world where governments continue to “print” and issue more government-backed fiat money.
Freedom and flexibility
Cryptocurrency is not controlled by any government or bank; it can offer a degree of freedom and flexibility that is not possible with traditional currencies.
Payments (Reduce cost of transactions)
Many cryptocurrencies can reduce the cost of transactions, making it possible for people to save money on fees and exchange rates.
Community
There are communities out there that are built around cryptocurrency. It can be just as much a social movement as a monetary one.
DeFi (better engage with finance):
Cryptocurrencies can help anyone in the world, with only a phone and internet connection, engage in the financial system. There are many people locked out or unhappy with the current one.
A person in Argentina or in a country with historically poor financial management previously was at the mercy of their governments and central banks. Often these countries failed to manage their money and saw hyperinflation destroy their country’s worth, simply printing too much money that it became worthless.
For these people, their lifelong savings were destroyed by bad money management. With cryptocurrency, these people can “opt-out” of their native currency and buy Bitcoin or stablecoins such as USDC (pegged to the U.S. dollar) with the ease of a digital wallet and exchange from their browser. This has never been possible.
There are many other ways cryptocurrencies are being used, but these are the most common ones.
