I think there's misunderstanding here. Is there any one that compares life and Bitcoin? I don't think so. Nothing can be definitely compared with life but that doesn't mean we should overlook opportunities when one comes around us. It's natural for people to make fun of others when they tried something and it work out for them while other were reluctant to take action. Likewise, people who failed to act mock them in return when it back fire. You don't have control over that. I don't care whether people invest now or not, their financial decision is solely their own responsibility.
Learning from experience and lessons of the others is better than learning from our own experience and money.
By learning from the others, we can save our time, save our money and avoid loss as much as possible but surely experience only can get by time and our own experience. For example, a newbie if don't learn from the past, will not know about Bitcoin market cycles, how psychological effects work in a cycle and so on. If he only learns by himself and own money, perhaps he needs more time (almost sure) and makes more bad mistakes, then loses more money by faults.
