Making a profit from long term saving in bitcoin proves to be dissipating every day since the price goes between up and down really quickly, saving long time proved to be good for people who invested in bitcoin a long time ago, right now short term is the best at making profit.
Current fluctuations indeed offer a great short term profit potential, but the thing is that you should know what to do. In most cases people are losing as they don't have a clue of how to play the market. It's not for nothing that only a small number of people manage to actually make profits. The profits these people make come from the majority of the other people that are losing. If everyone was an expert in trading, the entire market would be unprofitable.
