It seems to me that this is a normal course for such a large currency, now the bitcoin rests and no one can definitely say whether it will return to its highest price. In my opinion, he will return, but before that all those who are not sure will sell their savings.
I don't think that's the story here. How do you define "large currency". Just with the price or volume of the price? No, that's not the way things are. Bitcoins is most definitely most expensive currency but the usage of Bitcoin is still not large compared to other large currencies (dollar, eupo, chinese yuan etc). All savers who are in doubt wont not need to sell themselves off to set BTC in higher price, but they are the one who will keep holding which gonna cause the rise of the price.
