Trading can lead to disastrous consequences if it is done recklessly and without knowledge. Researching and scrutiny of the stock or crypto one is buying and seeing their past performances, vision for future of the company and other things need to be considered before entering the market to buy and trade. Also setting realistic profit goals is necessary as if we want to buy and then sell at too high a price, it will give frustrations when we see the stuff that we bought is not hitting that desired selling price "soon" as it takes time which demands lots of patience.
