buy memes also with a lower value for example, Shiba, Pepe, Doge, others also like Chailink, TRX, Shiba today has already given me 30 reais in profit, invest in memes for the medium and long term

Is there anything I can do to profit, either in the short or long term? Did I do something wrong in buying these amounts of these 3 bitcoins? Which ones are worth it and which ones are not necessary now?
