Only uninformed, desperate individuals only put their life savings into bitcoin. Unfortunately, there are some. But your claim on bitcoin is a ponzi without actually backing it is intellectual dishonest. I bet you're just whinny about your transaction and didn't consider some things like this is an open source project and almost all of the efforts going on are voluntary. People here are diverse.
It is clearly a ponzi scheme looking in here. Nothing but lots of people being busy talking up the price spouting messages about how this will finance their house and car or other posts about how you can convince friends and family to "invest" in Bitcoin as well. The more people are brought into it, the higher the price.
Oh, it is abundantly clear what is happening here. Some very smart people have bought bitcoin and are perpetrating a long-term pump-and-dump where they are slowly selling out while they ride the curve upwards. The ones being left holding the bag when the whole thing collapses are the ones who are indeed uninformed desperate individuals who are then left even more desperate not only having lost their own savings, but also stand with the shame of being responsible for friends and family suffering losses as well.
So yes, people in here are diverse. Some are preying on the weak, and some are being preyed upon.
