This idea that young people should be more circumspect ignores basic tenants of the time-value of money, and how life and responsibility work. When you are young you have the most amount of time to make up for losses and mistakes. You are also far less likely to have mouths to feed, a mortgage, and college tuition to think about. Things can get really bad if you are nearing retirement and lose even 15% of your portfolio in a downturn. On the other hand you can lose 100% and even have to declare bankruptcy at 25, and still have plenty of time to get your life back on track. I am not saying that Bitcoin or anything like it is a good investment. I'm saying that it gets harder to take risks as you age, unless you've been very successful and/or lucky. But being either of those things probably required some risk taking in the first place.
