When a beginner knows that bitcoin is expensive, it implies error from whoever is introducing him into bitcoin. There are some unnecessary information you don't need to release to a newbie which he will definitely learn in the process but by then he must have understood the system and also understand that bitcoin price does not mean anyone must have 1BTC to be an investor. Learning bitcoin investment from the wrong hands is worst than not learning at all because it affects all your activities and perceptions about bitcoin and often can lead to a permanent withdrawal from bitcoin investment. It's even better to trick a newbie into it than give him a demoralising information that could make him doubt the entire process.
Why will you trick a beginner about bitcoin investment, are you the owner of bitcoin? or you think bitcoin is one of those shitcoins that newbies are being brainwashed to invest in?. What is the knowledge you even want to hide from a beginner in the first place. If you introduce bitcoin to someone and you didn't tell them the whole truth they need to know before investing, any problem they encounter along the line you should be ready to bear the brunt since you introduce bitcoin to them without giving them a proper knowledge of what they invested their money on. True that learning bitcoin investment from a wrong person is not good because they will still trick you to believe so many things that are not true and you will only get find out after you have invested already.
