We both know that these two has many differences, in terms of earning it, spending it, transferring or converting it. In every aspect I mention earlier, bitcoin has an edge compared to physical money. Physical money is hard to earn unless you have a higher position. Transferring bitcoin to a digital wallet is easier compared to physical money. Even converting it, bitcoin has its advantage. But both of these are money, we can use this to invest, to buy what we want or we need. We must save them so when the time comes poor, we can invest.
