It's good to view bitcoin as a good asset but when you said that it would keep going up that may be an overly optimistic and bullish expression, it's bad to view bitcoin like that as tho they aren't times that the price may seem to be only reducing too and all this doesn't matter and shouldn't concern you if you are just starting out with bitcoin, IMO there are a lot of other things a new investor should be more concerned about than price movement which should be to get started buying bitcoin and figuring out how much you can invest in bitcoin without been affected by it, its more advisable to invest with your disposable income which I preferable view as money I won't miss or like a savings in bitcoin and that is because no one wants a situation whereby he needs the money he invest so soon or might want to touch or sell portion of his bitcoin and also in a senerio where anything can happen to bitcoin you won't be so bothered about that or be in a mess.

I believe that these should be your concern now that price movement or been too optimistic that bitcoin would only go up than down, yeah there are also such possibilities but I prefer not to talk about those, but one thign you must remember is the only way to prepare for up is to have more bitcoin .
