investing in crypto does not give you profits overnight, the day you plant the seed is not the day you eat the fruit, if you start today in 5 to 10 years you will have fruits

I am new to this world. I invested 150 three weeks ago and I don't see much gain or loss. It remains stable. How can I increase my profits? What buying method do you recommend? Thank you, I will now invest 150 more, what do you recommend?
