I received a payment about 18 hours ago, and it is still unconfirmed. The transaction log is here:
https://blockchain.info/tx/b6deeee2d2bc1b015aa3d73346216cd90dbcd5bda3943771fc5377765ab15e25I know the low fee might be a factor that causes the delay of the confirmation. But there is another thing that raised my concern: the red label which says "Double Spend!" How can "Double Spend!" affect a transaction? From the info I found on the internet, it is not a good sign.
P.S. I found a transaction acceleration service called ViaBTC and had submitted the unconfirmed transaction to it 15 minutes ago. But I think it is still necessary for me to figure out the effect of "Double Spend!" so I opened this thread.
Your Tx has got confirmation. So, the "Double Spend!" does not matter to u.
The thing is, the same coin i/p of your Tx was used in some other Tx, which is not yet confirmed.
The Post from newIndia is said simply like this. the Exchange sends the transaction which is showing in bitcoin qt, not confirmed yet - and thoose coins are sended to you as double spend until the first tx gets confirmed and the blockchain knows the correct truth.
