Bitcoin
Pre-Bitcoiners spend their lives exchanging time and energy for government money, also known as fiat (by decree). This fiat money is legal tender and is required to settle taxes, pay salaries, or used in contracts. It is enforced through an implicit threat of violence. Just try not paying your fiat taxes and see how peaceful your government is. The US government goes a step beyond this, actually holding the world hostage by being the world's reserve currency. Similar to how Japan has spent the last 30 years going into debt against itself, the US has gone on a tear inflating the stock of dollars. This nominal wealth is created and spent to stimulate the economy and kick the can down the road to prevent recessions or depressions (aka massive deflationary events). Deflation has to be prevented AT ALL COSTS because debt expands in a deflationary world. The US debt specifically, which is already astronomical, would become as dense as a black hole if the economy were allowed to enter a deflationary contraction of the monetary supply. Unfortunately, cheap money and expansionary monetary policies have resulted in inflation, something I discussed in my post of the same name.
If you're a wage-worker, you trade your energy and time for fiat every day. As you do this, the government actively sabotages your purchasing power. They are, in effect, stealing your time and energy. The dollar you earned in your teens will have its purchasing power cut in half before you reach middle age, meaning you have zero incentive to save. If you're living paycheck to paycheck, traditional investment vehicles like stocks and bonds probably seem out of reach. So in essence, the only way to fund your life is to never stop working, becoming a wage-slave. This would not happen in a deflationary environment. Enter Bitcoin. Bitcoin was created as a rejection of a monetary system controlled by the corrupt state, a state that not only taxes you to pay the interest on their huge outstanding debt but actively front-runs your future purchasing power by making the money printer go brrrrrr.
If you're already rich, this is not a problem because while things like education are skyrocketing, your assets such as real estate and equities are going up in lock-step. You can sleep easily knowing that your wealth is preserved. That's why Bitcoin is for the plebs, for the person who doesn't know how they're going to save, and if they could save, they don't see why they should. Saving cash is like holding an ice-cube in a sauna; you get to watch as it evaporates.
This is where Bitcoin can provide a life-raft. Instead of trading your energy day in and day out for fiat, trade it for bitcoin. Get paid in bitcoin, or buy some every week. Not as an investment, but as a deflationary savings vehicle. Due to its fixed limit of 21 million and exponentially declining emissions schedule, the value of one Bitcoin will continue to rise. Bitcoin is a black hole that will consume the rest of the financial market. Countries are mining it. Countries are making it legal tender. Countries are banning it. Central banks are acquiring it. The network effect will not stop. Bitcoin is winning.
