The current lost in value is more market related than Steem related, the best thing you can do is either, help develop if you have any technical skills or invite your friends and family into the platform to increase our userbase!
Being an active member of the community also helps out, guiding newbies to increase our retention rate and cheer leading the dev team every once in a while when they post is not a bad idea either :-P
Big updates are coming to Steem in the next few months and we can expect a lot of price movements towards the green hopefully :-D
