However, investors with a strong trading mindset have already built an indestructible psychological fortress. They construct defenses with strict capital management, reinforce the walls with scientific trading plans, and use stable emotions to fend off external threats. This psychological fortress is not built overnight; rather, it is the result of countless practical experiences and the honing of trading mindset, ultimately forming a solid barrier. With the protection of this fortress, no matter how turbulent the market becomes, one can remain as steady as a rock in the contract market of the cryptocurrency world and progress steadily.
