Steem trend is quite difficult to break, you need deep pocket and lots of patience, even then sellers are relentless so you could end up being the one holding the bags. I think to break this trend they would have to do it as old times, they would have to pump SBD and use the SBD to buy on the internal market to absorb some of the circulating Steem. Given the the main routes for Steem are Bitcoin, KRW and lesser extent BNB, adding a SBD to that can reduce the amount of Steem in circulating thereby picking up the price with it. Some people are against this method but that has been the only really successful thing in the past that can maintain Steem price at a respectable level
