I tried to rebroadcast, but the tx gets rejected. Decoding this shows that this is because the second input has just been double spent in this transaction.

I find this extremely disturbing.



This was one of three payments sent this morning. I have yet to decode the oother two, but I expect to see more of the same. The same thing just happened to me.

Update. I sent three payments. One for 1BTC, one for 4BTC and one for 95BTC. The 4BTC payment was double-spent as shown in my earlier post. The 1 BTC payment eventually arrived. The 95 BTC payment did not show up on the API for a long time, and when it did eventually show up, I could see that it has also been double-spent. I include the tx here as documentary proof:

Thanks for any help Hola. I'm waiting for my BTC now 30 hours. No sign of any progress yet. Is there any way I can see my transaction hash if I didn't make note of it when I was doing the withdrawal? I have only reference from them in email, but thats it.Thanks for any help
