Why are you here in the first place in you don't think that bitcoin will rise up again?

Did you check the price of history of bitcoin? If you did then you can answer your own question. But to give you a perspective, bitcoin price is not parabolic meaning its not always going up. Sometimes it need to go down for price correction or adjustment like consolidation. Then you can decide if you want to stick to bitcoin or just go to altcoin system. But it looks like you are in for bitcoin, so I suggest that you get it because there is really a good chance that bitcoin will go up in the future.
