It must be hard to realize this, but @ned sold you a worthless company. Now that most of the employees have left, you only own a toxic brand, an open-source code repository, a mediocre website and a pile of coins that doesn't give you the power you expected. If you managed to regain the top 20 spots again, Steem would become a centralized database, and that would make it worthless.

Are you willing to shorten the SP power-down period to 3-7 days from the current period?

You're still clueless about Steem technology if you think less than 7 days is possible. It's not our problem that Binance, Huobi and Poloniex used their customers' funds to vote for your fake witnesses. They're free to buy Steem on @blocktrades or @bittrex if they can't satisfy withdrawal requests.
