first. blockchain.info have their own version of priority calculation. and it sucks so don't rely on it.

be patient. your tx shouldn't take any longer than 10 blocks to confirm (that's between 10 to 300 minutes.).

and yes they're treated as double spend because you broadcasted a tx with same inputs as this one. a node that doesn't have the old tx received new tx and relayed it to blockchain which treated the new tx as double spend because they still have the old tx in their mempool.

it's called market activity... no use asking questions unless the price crashes or jumps by 20%. even then the answer you'll get are merely speculations.

what wallet are you using? and ask the receiver if they're the one doing the re-broadcasting.

looks like there's two more transactions that paid abnormal amount of fee recently. found this at reddit.

both have 4BTC fee. received by blockchain one minute apart. if it's the same guy then they lost 23.5BTC.

did you remove the tx from your core? if not then that may be why those tx has not returned to your wallet. core automatically re-broadcast your unconfirmed transaction so your transactions will never be returned to your wallet.

to delete unconfirmed txes from your wallet, do this.

you can only wait for it to get confirmed or dropped from the mempool and returned to your wallet.
it have 169,411,911 priority which is very high. so it might get confirmed despite the low fee.

stick to one thread, please. if your tx gets dropped again it'll be returned to the sender for good. that is unless the sender is continuously rebroadcasting it. this happens automatically with core so if the sender is using core ask him to delete the unconfirmed tx.

that's the best fee needed to get a tx confirmed in the next block. 41~50 is good enough and can get the tx in the next block or two. 31~40 next 3-4 blocks, etc.

but then again paying 10 satoshi higher per byte shouldn't be to costly.

you can double spend the outgoing transactions if you have the required resources to do that successfully (which I'm still not clear what.).
or stop broadcasting them so that the btc will return to your wallet. you still need to wait though.

but I suspect you already know these.

what kind of "successful url shortener" owner needs $15 loan? what's the name of your site?

yeah. signature verified. now just PM Vod and ask him to remove his feedback.

oh. congratz on getting your account back. 

signature verified. but change that message to something more clear like "this is cryptohunter. today is xx-xx-xxxx and I have control of this account.".

that part about cryptohunter2 being inaccessible is odd though. but I'm not an admin so what do I know?

EDIT:
btw. you need to PM Vod with the link to your signed message.

you should be able to sign a message even while you're out of sync. if you can't then safe the private key so that you can import them to some other wallet.
or just post here using cryptohunter2 account. that should clear things up.

care to prove it by signing a message from the address on the first post page? it'll get your neg off.


you can change your pass as many time as you like. just don't abuse it.

yeah that's what I think. but what are you doing here? aren't you supposed to be hacked?  
or did the real owner get his account back?

fast.

you are correct. a tx that spends an input from an unconfirmed tx will have to wait for that tx to confirm first.


again correct. but it shouldn't take more than 72 hours unless someone rebroadcasted the tx every time the mempool drops it.


you wait until those txes gets confirmed or dropped from the mempool.


pay higher fee in your future transactions. to know what fee per byte is appropriate for the current situation, see this site.

EDIT:
oh, I see you're using bitcoin qt. qt automatically rebroadcast your unconfirmed transactions so if you want them to be dropped from the mempool (so that the btc will return to you.) you'll have to get rid of those unconfirmed transactions. read this post by shorena if you don't know how to do that.

@shorena
this one verifies.
also that email looks like a fake.

edit:
I'll just PM OP telling him to explain.

where did you install it to? that's where it is. we can't tell you that lol. but try this -> /Library/Application Support/Bitcoin/

yes they will return to the sender's wallet if the mempool drops the tx. you can however keep reminding the network about your tx (so that it will not get dropped.) by rebroadcasting it again and again until it confirms (read this.).

if you can contact the sender and they are somewhat trusted then you can try persuading them to send a new tx with higher fee after this one gets dropped. keep in mind that the sender can scam you. so if they're not trusted don't do this.

not highest priority. blockchain.info treats 0 priority as Medium Priority.
anyway that tx should get dropped from the mempool soon as long as there's no one rebroadcasting it. if you're the one who sent that then this may be a good thing because you'll be able to send the btc again with higher fee.
