3 fundamental things you need to ask yourself when buying a coin listed on an exchange:

1- Supply situation: When buying some coins, you think about how many times it would increase if it returned to its all-time high after dropping 95% from it. However, most coins increase their circulating supply during this time, and while the market cap reaches its all-time high, the price doesn't even come close to the previous all-time high. Although this may seem like a simple topic, unfortunately, most people are unaware of it.

2- Community and Volume: Especially low-volume coins with inactive communities have recently been delisted from the Binance exchange, and recovering after delisting is nearly impossible. The risk of inactive coins is very high.

3- Reaction to Decline and Rise: This was a mistake I made in my time; it's important that when buying a coin, it should not drop significantly during a decline compared to the average. Generally, those that lead the way during an increase are the ones that suffer the least during selling waves. When a coin is overthought, more upward bars are drawn on the chart, but it’s essential to remember the feasibility of this. A solid foundation won't hurt.
