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.
