I feel like this is the most important one, especially for beginners like me that still don’t have much knowledge about it, so for my little understanding, understanding bitcoin is supposed to be the first thing to do as it will be one to guide you on every step you want to take on your investment journey in both security and everything else, so you can see that after you have learned all these things, the next thing you will think of is to hold bitcoin as much as you can afford to lose because you will confidently store it in a safer wallet.
