It is very rare for traders to get rich overnight, because all things need to process through time even in a few days, because not all coins can be hype as we want, so stay away from the concept and desire to get rich overnight because it is a very difficult thing to happen even though it is not impossible to happen.
You are definitely correct, you will not get rich overnight unless you win in a lottery, kidding aside. Thats really part of the game actually. FOMO and hyping a coin really spice trading. We tend to believe we can be rich but in a long period of time i guess.
