This time around, if it ever will happen again for STEEM I am afraid a lot more people will be prepared for it and the selling pressure will be enormous.

Consider what might happen when/if BTC goes to $200,000 at the peak of the next bull run. Even if a fraction of that goes into alts, that's a lot of money potentially flowing into STEEM if the platform has its ducks in a row. i.e. SMTs and communities up and running and an effective marketing strategy in being implemented to get websites to adopt SMTs to tokenize their content. Crypto media reporting widely on these successes could cause speculators to pour their BTC into STEEM.
