I don't think it'll go up at any time. It will be a reliable low value currency, as long as there are projects like Steemit to use it. Here and there the price will go up, as some rich Forex trader tries to singlehandedly change the market and make it seem like Steem si going the BTC way, basically scamming everyone into investing, and then selling at the highest point. It's happened before, it will happen with Steem - sadly, an incident like this will keep future investors away, fearing they might lose their cash with such a volatile currency.
