The altcoin will rising in the future, no need to worry. When bitcoin's down, some altcoin's down too, but not all altcoin's going down because the altcoin's trying to recover in a hard time if you check the market. This year, Ethereum cannot increase because Bitcoin is not rising higher, and Bitcoin is simply moving up and down. But if bitcoin gets a bull run, ethereum will also have a bull run time with the other altcoin.
