Well, first of all, it is not worth investing the last money if you do not have savings and a deposit in the bank. If a bank goes bankrupt, the state will return the money to depositors, but there is no such insurance on the stock exchange, you can lose everything. Moreover, the fall in the value of securities occurs much more often than bank failures. You can read about effective strategies for investing in stocks at https://daytradereview.com/seeking-alpha-review/, but I would advise you to start with the simplest strategy - buy securities, and sell them at a higher price after a certain time. It is worth noting that it is not luck that plays a key role here, but how well you analyze the market.
