Why would any average person want this? Yesterday, on a business/investor site, there was a headline that stated: "Bitcoin roars past 50,000." Well, by the end of the day it had dropped below 50,000. And can I just hand over 50,000 to own one Bitcoin? No. I have to play a game called "mining." I have to solve a puzzle in order get my Bitcoin. And the more people who want a Bitcoin, the harder the puzzle.
What's actually happening is money ownership. Yes, in the U.S., someone owns your money. Prior to a private national bank issuing paper currency with the words Federal Reserve Note, there were United States Notes. So, today the Federal Reserve owns the money and gets a cut from it. Prior to that, the U.S. Government issued and owned paper money.
Back to Bitcoin. Even though it does not exist as a real, physical currency, there is not an unlimited supply. So, who controls the number of Bitcoins issued? Don't know.
If I have 100 Dollars U.S., it will be worth 100 Dollars into the future. With Bitcoin, I give them real money in exchange for what? A Billionaire plaything? No. Definitely no.
