Multiplier contract: returns 111%-141% 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 0.01 to 10 ETH
- min 250000 gas limit
- you are added to a queue
2. Wait a little bit
3. ...
4. PROFIT! You have got 111-141%
How is that?
1. The first investor in the queue (you will become the
first in some time) receives next investments until
it become 111-141% of his initial investment.
2. You will receive payments in several parts or all at once
3. Once you receive 111-141% of your initial investment you are
removed from the queue.
4. You can make multiple deposits
5. The balance of this contract should normally be 0 because
all the money are immediately go to payouts
6. The more deposits you make the more multiplier you get. See MULTIPLIERS var
7. If you are the last depositor (no deposits after you in 20 mins)
you get 2% of all the ether that were on the contract. Send 0 to withdraw it.
Do it BEFORE NEXT RESTART!
8. The contract automatically restarts each 24 hours at 17:00 GMT
9. Deposits will not be accepted 20 mins before next restart. But prize can be withdrawn.
So the last pays to the first (or to several first ones
if the deposit big enough) and the investors paid 111-141% are removed from the queue

Контракт Умножитель: возвращает 111%-141% 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 0.01 до 10 ETH
- gas limit минимум 250000
- вы встанете в очередь
2. Немного подождите
3. ...
4. PROFIT! Вам пришло 111%-141% 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 111%-141% от своего депозита
2. Выплаты могут приходить несколькими частями или все сразу
3. Как только вы получаете 111%-141% от вашего депозита, вы удаляетесь из очереди
4. Вы можете делать несколько депозитов сразу
5. Баланс этого контракта должен обычно быть в районе 0, потому что все поступления
сразу же направляются на выплаты
6. Чем больше вы сделали депозитов, тем больший процент вы получаете на очередной депозит
Смотрите переменную MULTIPLIERS в контракте
7. Если вы последний вкладчик (после вас не сделан депозит в течение 20 минут), то вы можете
забрать призовой фонд - 2% от эфира, прошедшего через контракт. Пошлите 0 на контракт
с газом не менее 350000, чтобы его получить.
8. Контракт автоматически стартует каждые сутки в 20:00 MSK
9. За 20 минут до рестарта депозиты перестают приниматься. Но приз забрать можно.
Таким образом, последние платят первым, и инвесторы, достигшие выплат 111%-141% от депозита,
удаляются из очереди, уступая место остальным
