Can we assume that there will be a zero interest rate policy again in the future? I am 19 years old, am doing my IT training and would like to invest in real estate afterwards, but the costs would otherwise be too high.
not sure if this will be valid for you to expect , what I do believe that it will take you some years of waiting and if this will take you another years before that training and investing comes? surely zero interest will not be coming your way.
why not consider invest in crypto instead ? because in this place you are now and can find what are the best for your money and make profit.
