whatever the advantages of digital currency compared to conventional currency, digital currency will still not be able to replace the function of conventional currency as a legal means of payment. for me making a digital currency like bitcoin as an investment vehicle is very enough because the functions of the two are indeed different.
That is the case for now, of course, because of Bitcoin's volatility, most people see it as an investment asset more than a cash payment system, though it was created for the purpose of serving as a peer-to-peer payment system to transfer money back and forth without involving a centralized authority or giving any sensitive information to anyone only to keep your money safe, before Bitcoin, there was no decentralized mode for storing your money.
So we are yet to see a lot of things, Bitcoin being accepted as a payment method globally is one of them. So, we should probably just wait and ride the waves, for now, to gain some profit and keep storing Bitcoins while they are cheap, once we reach the time when Bitcoin becomes a global mode of payment, it will go too high in terms of price.
