I've been using bitcoin for the past year since I started sports betting and playing poker at bitcoin gambling sites. Any money I've won I've withdrawn and kept in a secure btc wallet. Because the price of bitcoin has performed so well, the dollar value of my winnings has doubled over the past year. For this reason I plan to keep any money I make online gambling in bitcoin so I can benefit for future price increases. While many of you may think this is a risky approach given how volatile the price of bitcoin can be, this money is just a fraction of my overall saving so I can handle the risk. What I find disturbing is the number of stories I've seen on forums and Reddit recently where people are taking out loans from banks and maxing their credit cards to buy as much crypto-currency as possible. This seems grossly irresponsible and makes me think that we are entering into a price bubble where many people will end up losing everything.
