I kindly ask my brothers and sisters with experience to give me advice. I currently have 3 currencies in my portfolio, and I have put 2 dollars in each of them. As you can see in the picture below, they are currently making a profit. Should I sell them now for this profit and buy again when the market drops, or should I withdraw a dollar from each currency and buy three new currencies, making a total of six currencies? I kindly ask for your advice. I hope each of the six or so people reading this topic will give me their perspective, as I am new to this market and the six dollars represent three months of savings.
