Well, I wouldn't think so. We have all seen the potential of bitcoin, but the majority of that 'richness' could only have been earnt if you had invested around 3-4 years ago, when the price of bitcoin was fairly low. However, that is needles to say that it is never too late to invest in bitcoin. In the past week or so, we have seen a ~20% value increase, and we can most certainly expect more of these to come in the future. The only way bitcoin can currently make you rich is if you hold onto your coins for a really long period of time. But you will soon realise that you can't hold onto all your funds and eventually you will need to spend some of it.
Not really because it is just a stepping stone to achieve someone's goal but not totally instant way to get rich. The only reason why others stick to this is to meet their satisfaction or needs for the benefit of themselves. There's no instant way of getting rich. It requires a lot of time to work hard, work hard means giving your time to post something about bitcoin. It's just the same when you work. Not all people become rich because they do nothing therefore do something when you want to get rich.
