Topic: [ETH] EtherDoubler.com - the first doubler with verified contract (Read 2531 times)
Is this contract still active? I see the website is gone, but contract should still work right?

I'm seriously dumbfounded why this contract is so popular. I have a much superior pyramid I made a few days ago, you can find my posting here if interested, but the code behind this pyramid is terrible, and the intentions of its creator are questionable.
Take for example:
Basically this piece of code ensures the first person's investment goes fully to the owner, guess who the first person that invested was, the script writer himself. So technically, the script writer gave himself a 3x payout, because he invested 5 ether, and got a total of 15 out of it.
Here's an example of how your payouts are being severely undercut:
Let's say you invest 1 Ether.
2 * (1 - 1/10)
2 * (0.9)
1.8
This is a "doubler" contract, yet your payout is only 1.8x? False advertisement much?
The next issue, and most major one of all is that the contract is only capable of ever paying out one person at a time. This means if there's 1 million people in the pyramid, waiting to be paid out 1.8 Ether each, and someone comes into the pyramid and puts in 1,800,000 Ether, all the others in the pyramid, should be paid out right? Keyword here, SHOULD, but they are NOT. This contract would ONLY pay out 1.8 ether, to ONE person after the 1.8M enters the pyramid. This means, for the other million to be paid out, irregardless of how much is in the pyramid, it would take another 1.799M addresses to enter into the pyramid.
This is a scam pyramid, whether on purpose or by way of bad coding. If you'd like one that is more sure fire and actually has had vigorous testing on the testnet, look into my Dynamic Pyramid.
Take for example:
Code:
// collect fees and update contract balance
if (idx != 0) {
collectedFees += msg.value / 10;
balance += msg.value;
}
else {
// first participant has no one above him,
// so it goes all to fees
collectedFees += msg.value;
}

Here's an example of how your payouts are being severely undercut:
Code:
uint transactionAmount = 2 * (participants[payoutIdx].amount - participants[payoutIdx].amount / 10);
2 * (1 - 1/10)
2 * (0.9)
1.8

Wow it's work! Now I have x2 my ETH!
I am glad to see it has really worked for you mate! I will give this a try and post back my experience about it. Since this is managed by a smart contract, it should be a safe bet to prevent owner from running away with the ETH.

I love this it took a few days to get my payout (360) but its great and thanks to it being run by the smart contract there is no chance of the creator running off with the ether like all the bitcoin ones.

I'm guessing this is where people who can't afford to make bitcoin ponzi schemes come post. That is saying much considering those ponzi schemes take only around a buck or two to make .

strait up pyramid scam...these are illegal. good luck not ending up in jail 
lmao it's actually utilizing the Ether functionality of contracts, the funds are not under the control of any person so no one could be jailed and even so the government would not waste their time going after a mini ponzi like this ever.

So is this like a ponzi or some shit like that?
Either way, wrong section.

It is not ordinary ponzi. All logic performed by Contract on decentralized Ethereum Machine.
Participants' funds are never under the control of the creator but are instead held by the Doubler contract.
In any case, you can try
