Money is supposed to be a medium of exchange, unit of an account, and a store of value. However, our money today is far from a store of value. Nowadays, people must earn their money twice: first, work to earn a paycheck, and secondly, figuring out a way to invest a portion in assets or financial products because their money lose value due to inflation and currency debasement.
It's even worse than that.
You first have to earn it. Your employer pays tax on every worker he employs, so he has to cut your pay to be able to afford to pay the government.
Then you are taxed on your share. First they tax your income, then they tax products you buy with that income with different taxes like excise.
If you put the money in the bank you're taxed with inflation.
Put it to work in a brokerage and you pay tax on whatever you make from it.
The answer is bitcoin - hold it and nobody knows you own it. If by any chance it grows in value significantly you'll be able to go somewhere where there's no bitcoin tax and live like a king and should you decide to leave it to your children they won't have to pay any inheritance tax and hold it for as long as they like. It's like an untouchable and uncontrollable vault that holds your wealth.
