Bitcoin's volatility has been steadily decreasing over time, which means huge price movements upwards are less likely than ever. Sorry it's not going to happen. I think 5000-6000 range is the correct or fair price, so selling at the higher end of this range would bring profit at least and then I think alt coins start making more sense at that point
