The market has no easy gains

The first money I invested was in a currency called Doge, which is a meme coin, and I currently do not recommend investing in this type of currency at all. At that time, its price jumped for two days, and I bought it at 0.4, and then it became 0.48 in two days, and it will reach a dollar. This is supported by Elon Musk and strong people... I thought I had become a great trader after a week... the price dropped by half, and I understood that there is no such thing as guaranteed profits, and if the market rises quickly... it can fall even faster.
