What is your most important crypto advice?
Please share here and also add a short comment why it is your most important crypto advice.
My most important crypto advice is "not your keys - not your coins" because it is simply a very important advice, where we should be aware to have real access to our coins and don't need to rely on a middleman. Bitcoin is clearly designed as a P2P currency.
Let's make it simple. Since everyone shared their brilliant crypto advices, I've got only one to say, do not just follow blindly but learn to verify them as well. With personal experience, you will learn all of that without doubts.
