You have a few years to retire or absolutely refuse to accept any risk of your savings decline.
Your savings from II. pillar will be obviously with a retirement from I. Pillar only one source of income in old age, therefore we can not gamble with them.
Restful sleep with minimal risk (minimum yield) is your priority.
Financial risks are unacceptable for you. The revenue besides with risk of devaluation of equity is for you a secondary problem.
You prefer the "old good" financial market products mainly focused on insurance and slow but certain accumulation of savings.
In the system of old-age retirement saving you save only in Bond Pension Fund and no one in the world will convince the more risky fund.
