Cryptocurrency is freedom and it allows me to do whatever I want because it's decentralized. I am free to pay for anything I want. I am very happy that cryptocurrencies can protect my privacy very well.
Crypto was originally created to provide free space for its users to make payment transactions without being related to the banking system, but gradually the use of crypto is more likely to turn into an investment alternative due to regulatory pressure from many governments today, but I personally prefer to see it as an investment which is advantageous compared to its basic use as a payment alternative for now.
