There is a new site, which will send double the amount of your payments back to you.
DoubleBot.comI can say that this site is paying and it is a really good one.
All payments proofs you can find on the main page.
There is a first-hand inforamation - you can earn a lot on DoubleBot.com. I can say it as an owner of the site. All other guys in this thread or elsewhere cannot say it, because they are not inside the system.
After you will receive your payments, you can say me "Thank you" below in this thread for such a good system that I created for you. It will be pleasant for me

+++ AN EXAMPLE
Trading bot can take 100 BTC invested and sell it for $241. Than after time, when the price will move down, It can buy more Bitcoins for $232 (for example).
Fee is 0.2%.
(241 * 100) - (241 * 100) * 0.002 = $24051
(24051 / 232) - (24051 / 232) * 0.002 = 103.46 BTC
The income is 3.46%
No Ponzi, but still profitable. Magic.
Will it be just 1 BTC or 1000 BTC, the income in percents will be the same.
I know that it is legit but can you please enlighten why it takes 1 year to double your earnings? I invested 100 Bits and it took almost 1 year to receive 200.
