Bitcoin is fairer than most currencies however its not the perfect system. The perfect system in my eyes would employ a type of socialism approach rather than the current "rich get richer". I don't think anyone can deny that you need a large investment to now mine Bitcoin. Of course this wasn't always true and anyone with a computer had the potential to mine Bitcoin when it was worth a lot less than it is now. However because of the mining difficulty increasing and will continue to increase in the future with emerging technology being able to mine quicker and more efficiently with higher hashrates we will price out those that can't afford these rigs. Bitcoin was initially mined on laptops and computers however we have since moved away from this and it now requires specialized mining rigs to be running 24/7 to be able to earn anything worth while. Unless you are using your mining rig for heating this can become a very expensive "hobby" when combining other bills too. There's now warehouses full of mining rigs in countries in Asia because the price of electricity is so low.
And I strongly believe usd is the most powerful currency ever in the world as claimed by POTUS simply because the absurd inequality in distributing the USD, and the top elite simply can print 99.9% of the USD while 0.1% of USD distribute to you and me.
This is wrong. The most elite cannot just print money off for the sake of it. The only people in the United States that can print off money legally is the U.S Treasury which is in charge of printing off money. However they can't just do that as they please as the governing body of money is called the Federal Reserve Bank which has control of the money supply through its ability to create credit and interest rates. The FRB actually control all money which is sent off to the banks of every major country in the world. Remember that if you print off too much money the economy becomes unstable and we would probably enter a recession which would further devalue the amount of money everyone owns and therefore printing off money isn't the solution to everything.
Cash is backed up by gold and what cash is is basically a IOU note which you give people to promise them gold. Gold is moved around from time to time but imagine paying for your groceries in gold it would be a nightmare. Instead we carry the much lighter and lower value cash.
