We have one up top who has given his reason. And it does not look good. The cost of running the witness is much more than his earnings. Screenshot below. You can scroll through this post to see for yourself.

So I see it this way.. if you run a pizza shop and it costs you 10,000k a month to make it function. But the pizza shop is only earning 1k a month take in. You would not be able to sustain the business for more than a short while.

In my opinion this can not be taken 'many ways' only can be taken 'one way' which is Steem is unsustainable. And there is a HUGE consensus in the matter among witnesses even if they do not verbally admit this. Their actions speak LOUD and CLEAR. They do not want to cause panic and have all the little guys sell off.. or the price will tank and they will not even get their little 0.40 usd cent per Steem that they can at least get out of it at the moment.. they have both 'reason' to pull out, as well as a 'motive' to attempt to hide it.. aka wallet split condenser..

If you think people are not foolish enough to 'not notice' then I ask you this.. why did NO ONE hear about it until I said something? Name me one post on Steem that covered this topic. You won't be able to. That is because it was attempted to be kept hush hush.. and the powerdowns all came in concert like a water ballet by the witnesses.

I guess you think it is just a magical coincidence that 60% powered down immediately after their wallets were moved off site.

At any rate I appreciate your comment. Thanks for sharing. Take care man.

ps the screen shot of what the witness said is down below. Hope it helps shed some light for you.
