Everything in the world is a game, I would say. We need to maintain balance while we play. Once we know how the game works, we use it in our day-to-day lives. Similarly, Bitcoins are a financial game. Unlike any other investment, we can do Bitcoins in order to make some extra bucks. But yes, we need to understand the risk involved in it and invest in our capabilities. The market is always volatile; hence, we should invest only that amount in Bitcoins that we can afford to lose.
