Don't think of something impossible or hard to achieve. It's better to set more modest goals that you'll be able to accomplish than something that will end up failing you. With the ability to double your funds in such a short time, you are likely to take too much risk to lose. Bitcoin isn't the weapon to get rich over night, no matter how tempting it is.
Actually no one know what Will happen to bitcoin in this and that year became bitcoin is unpredictable that no one know what is going to happen. I think we should focus on buying right now because yet market is so volatile and no one when it will stop to bullish so better keep patience and an investor should not be that greedy to get rich in days or months it takes time to achieve something huge.
