Yes there are other coins that change their price faster. Some of the altcoins can bring you huge amounts of money. But the problem is, that you need to find out which ones are good.
I think at the end of this year some big players will come to the markets. There will also be ETF's about cryptos that will be tradeable, so I think Bitcoin will rise again.
It's mostly bad to panic if prices drop. Of coure if there is a bad ICO in that you invested and prices drop it's understandable. But you shouldn't panic from dropping bitcoin courses. They will surely go up again with the ETF's.
