I don't understand; in case of double payment problem the script should block and wait for some input, then on the weekly ponzi site is indicate that I have been payed but this is not true ..... I send the BTC without double payment issue, why I have to loose all my money for a script problem (this problem happen on 24h too and as been solved many days ago, why is still present on weekly ?).
Such features are built directly into the bitcoin software, because that's where such logic should be. There is no "double payment problem" and the chance for a "double spend" in bitcoin is near impossible. The bitcoin network can drop TXs if they are never confirmed or become orphaned, this is regular and happens all the time.
A few steps:
1. Send BTC to the 1Week8mnA address.
2. Wait for return on investment.
3. Did investment return?
Yes:
Done.
No:
4. Check for unconfirmed transactions, if your payment is not confirmed it may be dropped by the network. Your payment may be dropped, but the funds remain!
No:
You've lost, done.
Yes:
Return to step 1. See historical example where this worked out for 1Exca117ik6cR2mySwfpz4GGrUGRx5p3Eh
The above steps are proven to work.
