Deciding on which coin to buy at the last minute, and just when I wanted to place an order, the platform data kept loading and wouldn't come up. I watched the market move away right in front of my eyes, and I missed out. This feeling is really terrible — it's not about not being able to predict the direction, but about failing in the execution phase. I hope exchanges can improve data stability to be more reliable; otherwise, even the best market conditions are useless.
