Real money is accessible everywhere but bitcoin requires internet connectivity to use and its accessibility is limited and huge population unaware about bitcoin and crypto currencies. You can buy your everyday needs through cash any time but that is not possible through bitcoin.
the decentralization in bitcoin make a big difference , real / conventional money are regulated under government/certain institution . so your money are in the third party. bitcoin gives you discretion , a full access to your money , used globally and has no tax in it ( which it's still become a pros and cons ) .
Yes, that's true. especially when government devalues currencies, it tends to go down on our investments. to be in control is very great.
