There are pros and cons of both.
Cash
It's easier to tamper with taxes
The state can not rob you as easily
It´s slow to move and transfer
It weights more
You dont need to remember any password to carry your cash
It's easier to find cash if you lose them
Hacking proof
Digital Currency
It´s getting harder to tamper with the taxes. (soon impossible)
The state can rob is easier
It´s cheaper to move and transfer
If you loose your password = you cry hard
Hackers paradise - They can rob you (and the govs)
So which is the best?
I think you need a mix of both.
Don´t try to go 100% crypto currency.
Whether you are going to shop for food, clothes or anything else. Use cash.
Are you going to order goods online, then use digital money or if you are buying more expensive items.
if cash is completely lost, how can you handle a financial crisis?
The banks / state will take all your savings a lot easier.
Worst victims will be all new in the digital world who do not know anything about cold waller, paper wallet etc..
I love crypto and the idea of crypto.
But, It can also be a backlash for everyone.
Thank you.
