Investing and trading is somewhat risky for every new investor or trader. Initially, an investor or trader does not have a complete understanding of these issues, due to which newbies make more mistakes in investing and trading. In the first instance new members need to get training and practical idea about investment first. Beginners need to use small amount of money first to get real idea. When they can get a fairly realistic idea of trading and investing with a small amount of money, they can start their main investment or trading. But in the beginning if one goes for direct investment or trading then they will not be able to do any good from their trading. So every trader and investor should get enough ideas and practical experience in the beginning.
IMHO, when someone invests he already takes it as something risky even before doing it. And someone who doesn't have knowledge upon doing so is actually a risk taker. But do they know that they can minimize the risk that before doing an investment, researching is going to give them an upperhand.
Just to make sure that your hard earned money will be used properly and wisely, those that invests without prior knowledge are truly taking the top risk.
And relating that to Bitcoin and trading, many of them doesn't mind going to the point of trading as soon as possible because of misbelief that they can make easy money there which is truly wrong and doesn't make sense.
OP is right. Let them experience how this market butchers those that are unprepared so they will see the importance of holding and winning.
