There aren't many options where you can invest your money to secure a pension. If you save in fiat currency, you lose purchasing power day by day due to high inflation, and hyperinflation is possible, where you could lose everything in a short period. If you buy stocks or bonds, you are still dependent on fiat money. If the fiat system collapses in hyperinflation, the economy will sink, and stock prices will fall, and bonds won't be paid out. Bitcoin is the only safe place; Bitcoin is the lifeboat.
