I join in crypto few months ago, and i bought a lots of useless coin, i figured it out it not gonna make me money. So you have to be smart and buy coin after u do the research.
This is a classic mistake, people enter the crypto world thinking they can buy whatever coin they want and have huge earnings but that is most of the time not the case that is why it is important to always research in deep whatever coin in which you want to invest, I know it can be boring and it can be hard work as well but it is better to be tired and bored than to lose money.
Most of investors joined the cryptocurrency market want to make money fastest from this field, it made the speculators concentrate a lot here. So, not hard to see the FOMO and panic seller in this market. It always happens when the price of Bitcoin or other cryptocurrencies price fluctuates sharply.
