<prompt> Human: I live in an Eastern European city were the average income is 400-500 a month. I have an income of 1000 which is quite high here as the cost of living is very low. After all my expenses and costs I could easily lose 100 a month and not even notice. Id like to put this money to some use and invest.Is it worth investing 100 a month or will it be a waste of time? by investing I mean by using stock trading apps  <response>: If youre debt free except a house, have an emergency fund of 3-6 months expenses, totally invest that 100. I dont know much about stock trading apps or their worthiness. But I do know that investing even 100 a month through your working career is MASSIVE to your retirement. It really really is. Totally do it if youre in the right position to invest
