Independent Research: Before investing, please thoroughly study the fundamentals of Bitcoin and blockchain to understand what you are investing in.
Information Source: Be cautious of 'pump and dump' schemes and overly emotional market opinions on social media.
Safety First: If you decide to buy, use a reliable major trading platform, and consider transferring large assets to a hardware wallet where you control the private keys.
Ultimately, the decision is in your hands. Operating near historical highs is more like a game of probability and psychology. Be sure to make prudent choices based on your own risk tolerance, investment goals, and financial situation.
