Compared to fiat currency, Digital currencies are very powerful in-terms of control. You can control your own coin. There is no interference from the government, no one can rob it or counterfeit it. You can use it globally and expand your business internationally. I don't find anything more powerful than this! what is your thoughts on it !
on certain parts, digital currency is indeed powerful, but because OP only mentioned digital currency in general not specify it like Bitcoin, or Ethereum, or others, not all digital currency is uncontrolled by Government, there is a CBDC, and even worse some many cryptos are controlled by anonymous or proxy entity, with government we can actually take a legal action if we think we got cheated, but with some cryptos we can't really do anything if we lose money on those cryptos. Best option would be Bitcoin obviously which actually is decentralized.
Well, OP did not mentioned any specific thing but only a digital currency. I think any digital currencies is still considered powerful not only to Bitcoin or any crypto coins/token. Just imaging the convenience it gives like Paypal, PayMaya, and Gcash which I think some only exist on some countries. You don't have to hassle yourself by exchanging physical money into any transactions when you can do it online. That's true that some of them are can be controlled by the government, as they can put taxes and service fee into any transactions so it's like a win-win situation for them. Only difference with centralized and decentralized is the security and safety it depends on you and the government.
