Block chain has no future!
Keep cash cash is king and trusted money always
It is true that paper money will take precedence but no one can determine what will happen. just like when crypto with Bitcoin at that time no one believed it could be as valuable as it is today. everything can happen and no one can determine what will happen in the next year and only predictions.
but I agree that paper money is still the most important because after all it is the standard for our shopping and everything will also return to paper money even though you have how much valuable tokens
