It can difficult for anyone to go in to anything that they do not have any idea on, the learning comes in different ways the theoritical and practical, theoretically the basic knowledge is required to start to perform the practicals while learning continues gradually in both aspects, while having to know the basic theory of swimming will not make any one to know how to swim without practicing, alot of people who were courageous to jump in to swimming without taking the necessary steps never keep calm infact some didn't survived it and some too that survived never went back out of fear from their previous experience let's just say that there are steps to which the all of this of can be followed that will be reasonablely practicable including the leaning how to swim and going in to Bitcoin investment.
You don't have to get burnt first before you learn, because you might get burnt to the level in which you might never recover to bounce back again, that's why I believe that the best way to learn about Bitcoin or any other thing is by doing your own research, asking those that have been in the field earlier that are successful in it, and also ask those that has been in the field earlier that failed, they both have what to tell you because their experience differs.
Those Bitcoin investor that fails will definitely disclose so many things to you why he fails, like the mistakes he made and what he should have done, so as the investor that was successful, and all he has to do to be successful, so as long you are humble enough to learn from both of them if they will be sincere with you, you will never miss a step while investing in Bitcoin.
