Bitcoin is easy to understand. Money is your work and energy stored for the future.
You can choose:
A.) money created by a cabal of politicians, bureaucrat, lawyers and banker that is guaranteed to loose value over time at an unpredictable rate. You need their permission to own and use it.
B.) money created by the expenditure of energy at real cost with a fixed predictable issuance schedule controlled by no one and audited by thousands of people globally every 10 minutes. You don’t need permission from anyone to own and use it.
If both systems operate side by side and do what they are designed to do, then holding B makes you less poor than holding A. Both appear to be behaving as designed. Overtime all value accrues to the better money.
The trend is clear and the volatility is because of of the unpredictable rate of change in A and the learning curve as new people come around to the novel properties offered by B.
