Bigger common mistake

Too naive to invest by just follow a few rumour and meme post by commoners on stocks and buying cheaper price stock which become more cheaper. Bigger mistake to buying the dip with deeper dip and another dip until dry out wallets without knowing are the company really growing or joking. Another mistake is sell out the potential making profit company stock (apple, tesla, fb) to buy the cheap price stock (clov, clean e, futu, penny stock etc) 😅. Well hope to get well soon.
