Let me correct you. "Kim buys 8 BTC offer. Offer is automatically increased to 16 BC. Dave should get 8 BTC to his Bitcoin Address. But fee for the site is counted only from earned money. So the fee is 25 % from 4 BTC = 1 BTC. For the referrer goes 10 percent from earned money 4 BTC * 0,1 = 0,4. So the site gets only 0,6.
Final state:
Dave bought for 4 BTC, he earned 3 BTC and gets 7 BTC to his wallet.
Site gets 0,6 BTC and referrer 0,4.
Thank you, it is probably not very clearly written. I will change the OP.
As I said, there is still no fee for the first 10 transactions.
OK, so the fee on withdrawal isn't for the amount you withdraw, it's only when you withdraw profit?
The OP used to say:
At the start of this service are withdrawals charged by fee 25 % from earned bitcoins. After some time it will be decreased.
but now there's no mention of fees at all. It makes it look like Dave spends 4 and gets 8 to his Bitcoin address, which you've now said isn't true.
And it doesn't matter about the first 10 transactions - if this scam takes off that's not where the money will be made.
