even spammers were buying steem

Yeah, they buy that initial few hundred or whatever and just use the "profits" to continue to bid. You obviously have no clue how those bots work. Nobody would use the bots if they didn't offer a return.

All ROI from bid bots goes directly to steem power (its not liquid!!) and thus increases the size of the reward pool.

Horseshit. They have to pay their delegators. Do you know why many are always powering down?

But I doubt you'll do the math, even if I showed it to you.

You math? Last time I checked, you make "dictionaries". I can name at least two entities that bought more STEEM than your sorry spammers since the HF. The real math here is most the whales prefer to cash out faster than people buying/creating value.

You leaving won't make a difference.
