When you were a beginner, you made mistakes. But despite their experience, many people continue to act in the same way. And besides, as an online user, you should never disclose your login information. It makes no difference how close they are. That should be applicable to anything you have been using on the internet, not only Bitcoin. Just purchase a hardware wallet for Bitcoin to protect your assets. You should be able to purchase a hardware wallet, in my opinion. Knowledge and education are not the same thing. What you have just acquired is knowledge. Education is the way you become literate.
I guess this is the quote that summarizes your post at least partially: "
Insanity Is Doing the Same Thing Over and Over Again and Expecting Different Results"
I just learned that it is not proven that Albert Einstein said that. I always thought it was him. Anyway...
Education is the way you gather information and theory and turn them into accessible and applicable data in your head. Everything you can recall and use is what I would describe as knowledge.
This is why it is indeed a problem when you are an educated nerd for example in accounting and you know all the rules, but you can't apply any of them in real life set ups practically. You know what to do, but you don't know how to do it. But this is still a bit tricky though.
What if you know a recipe, a very complex one, for some food. You can't do it yourself but you know a cook who has no idea about the recipe. When you exactly explain him the recipe and the cook executes it, I guess that would just be education. The cook knows how to execute it because he can conclude from other recipes and knows for how long the specific ingredients must be cooked. So he has knowledge?
I guess an engineer is a better example because there it is more likely that someone knows what to do, but not how to do it. If a car is broken and perhaps I know what the problem is and I studied engineering, I know that part X within part Y needs to be substituted. Just knowing this probably doesn't get you anywhere if it is in the middle of the engine block. Then you probably are only educated.
Not so easy to come up with a sharp differentiation on my own.
