There's no real guarantees in this, and no one can realistically tell you what to do. The market isn't completely predictable, you can only make educated guesses as to where things will rise and fall and invest accordingly. I personally think bitcoin is still at a pretty decent price to buy in at, but I wouldn't invest every last cent right now, save 25-50% of your investment so you can buy in more if it drops, or even more really. There's lots of ways you can do it, but just don't trade with your emotions, trade with your brain and leave the panic out.
