If I knew then, what I know now about bitcoin, I would have approached this company, and demand that they pay me my pension in bitcoin, or don't pay me pension at all, but pay me my salary in full, and from my salary, I will create a bitcoin pension for myself.
I'll start from the very end. How naive you are. No one will give you your pension savings, no one will pay your salary in full, no one will pay your pension in bitcoin. But you can create a pension for yourself in bitcoin. Yourself. Just buying with free money.
The system is designed in such a way that people have no choice whether to pay part of the money from their salary to the pension fund or to form their own pension themselves. This is a worldwide practice. We are simply obliged to do this, whether we want it or not. In fact, contributions to a pension fund are another form of taxes (functionally very similar to a
tax on fools). This money is collected from all employed people for the entire period of their active work, but only a portion of it is paid. That is, the majority of people who paid pension contributions don't live to see retirement or don't live in retirement for a long time. Roughly speaking, the pension fund has collected 100% of contributions, but pays out only 20%. Profit.
Next point. This is inflation. Inflation hits these pension contributions stored in the pension fund. In 20 years, the money that will be paid to you in retirement will be negligible. In some countries (if I'm not mistaken, in Scandinavian countries), pension funds invest money in securities and even cryptocurrencies. But there are very few such countries. In most countries, your money in the pension fund will either be greatly depreciated, or you simply will not receive it or will only receive part of it (try to live and then live a long time in retirement).
I repeat. No one in any country has the opportunity to refuse to pay pension contributions. Consider this your
free forced gift to the state system. But there is an alternative. You yourself can create pension savings for yourself, which will increase every year (more precisely, every 4 years).
