That's normal so take some nice plan if you are into bitcoin investment and that will include holding and saving coins. We must play with the price fluctuations rather than to considered it as biggest problem. Without those price fluctuations, we can't earn good and decent amount.
And sometimes you need to take some risks with Bitcoin and that can be bad if you are doing it wrong.
Why you consider it as a problem? You should view it as an opportunity to earn some extra profits, I simply love fluctuations in bitcoin.
