i'm not saying it's not a ponzi, but why wouldnt they power down?? who wouldnt??
they have more than enough to keep using the platform, they will take 1/104 per week so it's just a parcel.... and the fact they are powering down it good to the community.. so what's the problem? they should keep the money there forever?
Usually when people believe in a currency they buy it they don't sell it. The fact that 90% of the whales want to cash out send a very clear signal to potential investors.
Why is everyone acting in the platform's best interest ( ie powering up) but the whales? Because the whales have so much money that they are in the greed phase already while the other people are still in the "let's make steem a success" ( for their own personal gain ofc) phase.
The bad news is that the numbers of greedy users is growing by the day ( I don't blame them btw) which means a decreasing steem price which in turns means more powering down.
Steem power is what holds this thing together, the more people powering down the quicker it will be break down. The people who will be left holding the bag are the one late to the party the smart ones on top are cashing out while the fools are buying.
