In life if purpose of thing is not known abuse is inevitable, I have come realizes that many people do not have purpose of purchasing bitcoin only buy because they've money and when anything went wrong they will be to lament or query people.
Buying bitcoin aimlessly - oh how did that happen?
The average trader buys bitcoin because they want to make profit regardless of how they develop their trading strategy going forward. In fact, I dare to say each of them bought bitcoin because have their own goals, so your assumption about things like the above are very unreasonable. Some buy bitcoin because they want to use it as means of payment - while others buy it to make profit.
Sometimes is good you ask yourself certain questions why am I doing this? What is my aimed for it?
Obviously - they think about it even if not all of them have the skills to manage it well. Bitcoin trading and investing is risky - sometimes you have to adjust your plan at a time and start over for some reason.
