I have met people, who nowadays are doing very well financially, because they got into Bitcoin very early (2009-2012).
The funny part, is that some of them end up using BTC for buying drugs on Silk Road site.
And, just a couple of days ago I met an American (70 years old) who has some BTC because he used to play poker in an online casino where BTC was used.
So we can conclude that having a small vice can benefit you financially as long as you can control your vice.
Or those examples, were just lucky people???
