I started when bitcoins were just $300. Back then the only purpose on why I bought bitcoins was that I needed to gamble with the bitcoins since my old bookie charge a huge margin compared to just playing on some bitcoin sports books like nitrogensports. At the time, it was not an option to play at the major and leading online sports books as it was terribly hard to deposit coming from my country nor do I have a credit card to deposit with. I feel bad though that I lost all those bitcoins back then, but can't really turn back time. Also, who would have know that after just a few years prices will come this high.
