There is no way to prove that until after many rounds have been made. It is up to you to lend or not. If you don't believe that it's not a scam then don't  send! It is simple!

It's up to you to trust or not.
If you don't believe that you will get your money + 25% interest in a week then don't invest.

You would have to trust that we won't scam you.
You are right to be sceptical. However we are not going to scam anyone. Be assured that we will stay here even after we have paid you out in a week. Also you can even reinvest your money in the next round and earn compound interest.

When people lend us a minimum of 2.5 Bitcoin or a minimum or 300 Litecoin, they recieve their initial investment + 25% profit after a week.
I understand why some might think that its a scam, but be sure that its not.

Its not a ponzi scheme/scam.
Investors will recieve their payout, unlike other threads. Because we actually make profit.
This provides us with leverage and liquidity.
Perhaps i should move this thread to a different subforum, because its not gambling.

Yes. Its not a scam.

Earn 25% Profit in 1 Week. Round 1

Faq:
Question 1: How can you make us 25% in 1 week?
Answer: We are good traders. And see when there are great trading opportunities
Question 2: Will there be a new round every week?
Answer: No. A new round will only be made when there is a great trading opportunity which can make great profits for all. So keep an eye on this thread.
Question 3: How do you make money from this project?
Answer: We gain great profits with your coins and only send you 25% on your coins while keeping the rest for us.
Question 4: Which coins can I invest?
Answer: Only Bitcoin and Litecoin are accepted.
Question 5: Are there any risks involved?
Answer: Yes. If the exchange we trade on does a mt gox then you will either have a delay in receiving your payment or not receive it at all. Unlikely to happen but it could. Also if a huge holder of Btc and or Ltc dumps Btc or Ltc to half its price in 1 order, or buys it up to double its price in one order then you could lose some coins. Unlikely but possible.
Question 6: How can I invest?
Answer:
For Bitcoin:
Send a minimum of 2.5 Bitcoin to 17wu33RGLDCBezGGWWNYmzw5RexZcGyw9K from your personal wallet (not from an exchange or web wallet)

For Litecoin: Send a minimum of 300 Litecoin to LcYg7mnBZtYEcCMmJoSj613kAQhvaB9J4u from your personal wallet (not from an exchange or web wallet)

After a week you should receive your investment plus 25% profit back to the address you sent from.
