High risk-and high reward. Currently, there are over 10,000 cryptocurrencies on the market, each with unique characteristics. Nevertheless, all cryptocurrencies share some characteristics, including their proclivity for abrupt price increases (and decreases). Prices are largely determined by the supply of coins from miners and the demand for them from buyers. This dynamic can result in substantial profits. The price of Ethereum, for example, nearly doubled from July 2021 to December 2021, resulting in a windfall for investors who jumped in at the right time.
Blockchain technology, which underpins cryptocurrencies, is intrinsically safe. The most significant advantages of cryptocurrencies aren't directly related to the currencies themselves, but to the infrastructure that supports them. A blockchain is a decentralized data-storage ledger that records every transaction. Once a transaction is recorded, it cannot be deleted. As the blockchain is distributed decentrally over several computers, no hacker can access the entire chain at once; any information held there is secure at all times.
Say goodbye to old banks and hello to a more equitable and transparent financial system. Third-party middlemen handle most transactions in our financial system. This implies that whenever you conduct a transaction, you're putting your faith in one or more of these intermediaries—and the early-2000s recession made many people rethink if that was a smart idea. Blockchain technology and cryptocurrency provide an alternative.

There are numerous advantages to cryptocurrency. The options are limitless and there is great variety and choice since as you correctly stated there are over 10000 cryptocurrencies.

Safety is indeed a considerable aspect, and I think that this is one of the main pros.

And when it coms to transactions it is all so quick and affordable, making it so much much better than traditional transactions with banks.
