In my opinion, whatever the price, it is wise to invest in steem. So many cryptos are dead investments because they do not produce anything else other than a profit from hike in price whereas steem allows you to earn from it.
Steem helps increase your power not only on steemit but also on apps like musing, and other such steemit based apps.
Investing in steem is wise now as the price is low.
By investing in steem, you are increasing the way your account influences and it can be regained or even doubled within a short time.
Good luck
