  Queue contract: returns 120% of each investment!

  Automatic payouts!
  No bugs, no backdoors, NO OWNER - fully automatic!
  Made and checked by professionals!

  1. Send any sum to smart contract address
     - sum from 0.06 ETH
     - min 350 000 gas limit
     - you are added to a queue
  2. Wait a little bit
  3. ...
  4. PROFIT! You have got 120%

  How is that?
  1. The first investor in the queue (you will become the
     first in some time) receives next investments until
     it become 120% of his initial investment.
  2. You will receive payments in several parts or all at once
  3. Once you receive 120% of your initial investment you are
     removed from the queue.
  4. The balance of this contract should normally be 0 because
     all the money are immediately go to payouts


     So the last pays to the first (or to several first ones
     if the deposit big enough) and the investors paid 105-130% are removed from the queue

                new investor --|               brand new investor --|

  Контракт Умная Очередь: возвращает 120% от вашего депозита!

  Автоматические выплаты!
  Без ошибок, дыр, автоматический - для выплат НЕ НУЖНА администрация!
  Создан и проверен профессионалами!

  1. Пошлите любую ненулевую сумму на адрес контракта
     - сумма от 0.06 ETH
     - gas limit минимум 350 000
     - вы встанете в очередь
  2. Немного подождите
  3. ...
  4. PROFIT! Вам пришло 120% от вашего депозита.

  Как это возможно?
  1. Первый инвестор в очереди (вы станете первым очень скоро) получает выплаты от
     новых инвесторов до тех пор, пока не получит 120% от своего депозита
  2. Выплаты могут приходить несколькими частями или все сразу
  3. Как только вы получаете 120% от вашего депозита, вы удаляетесь из очереди
  4. Баланс этого контракта должен обычно быть в районе 0, потому что все поступления
     сразу же направляются на выплаты

     Таким образом, последние платят первым, и инвесторы, достигшие выплат 120% от депозита,
     удаляются из очереди, уступая место остальным

              новый инвестор --|            совсем новый инвестор --|
                 инвестор5     |                новый инвестор      |
                 инвестор4     |     =======>      инвестор5        |
                 инвестор3     |                   инвестор4        |
 (част. выплата) инвестор2    <|                   инвестор3        |
(полная выплата) инвестор1   <-|                   инвестор2   <----|  (доплата до 120%)
