Major coins in my wallet

I just entered into Bitcoin market by December 2017. It was such a sweet ride but unfortunately, the last minute ride pulled back, and I just hold my investments and no profits. I currently hold below coins. My investment is around 10k USD. I appreciate if steemit readers suggest me any good coins to purchase and hold for long-term investment.

ETC
