CRYPTOS AND LEGAL TENDERs

Funny how the world evolves.. And how its inhabitants embrace change voluntarily or otherwise.. History of money can be traced to cowries and foodstuffs($imple life?) i.e barter system. I guess fishermen were probably the richest guys then.. All of a sudden it became gold from the goldsmiths. Atleast precious stones could store value. Women must have been really poor then. Wearing money up n down. However it became our notable domestic currencies which people could die for. Created a lot of problems as man became greedy coupled with capitalism where inequality was the trend(even though that was really not the whole idea) today we have cryptos. What an awesome idea. This brings to mind power to the yound and information savvy guys who follow trends. Badluck for those old men who keep money in huts and seawage tanks in Nigeria. Ur worth is not how big ur clothes are or how fat ur pocket is rather how wise you are in this market. With over a thousand cryptos already certainly cyrrencies are soon on their way out and cryptos taking over..BUT all these always started with someone's idea for a change. So after cryptos what next?
