People will always try to show off wealth and try to "fake it 'til you make it" has been around for a long time. I wouldn't say that Bitcoin is especially popular for this purpose, because it is hard to show off a "piece of code" compared to a loan spent to buy a flashy car or the latest piece of fashionable clothes that they can show around town. Either way it is better to ignore such trivial displays of wealth and concentrate on improving your own life.
