I sent a big amount in bitcoins 7+ bitcoins
I don't know what i did wrong
The transaction size is big i mean really big 16000+ bytes and the fees i paid was only 0.0001 btc
You should always pay a fee per (k)byte and not a fixed amount.
I am scared if even it will get confirm or not.I wonder if it's possible to rebroadcast or resent the transaction with higher fees?
Depends, which wallet / service do you use?
Believe me if i knew the transaction size can be that big i would have paid 0.01 btc fees
now what do i do frenss?
"frenss"?
P.S I control both the address the one i sent it from and the one i sent it to.Is there any way i can resent the transaction with high fee or just cancel this one or anu other way?I think I am screwed
Can you post the TX ID? That way we can see why the TX is that big, how high its priority is (not that bogus "high"/"medium"/"low" you see on blockchain.info) and will (together with knowing your wallet) help make good suggestions.
Wallet is blockchain.info wallet
and can't post the tx for privacy reasons.
Well, with bc.i you most can only wait.
But i can tell all the inputs were confirmed?
I need the size of each input and the number of blocks its confirmed. If you provide that information I can easily search for the TX ID.
If you do not want to disclose this information you have to calculate the priority yourself ->
https://en.bitcoin.it/wiki/Transaction_fees#Priority_transactionsthere was no unconfirmed inputs still the tx i just sent got that big in size.
and how do i know before sending what will be the size of the transaction so that i can set the fee accordingly as you are saying to pay according to per kB?
With blockchain.info? I dont know. I mainly use bitcoin core, it tells me how large the TX will be. A rough estimate is 180b*inputs + 32b*outputs for uncompressed keys and 134b*inputs+32b*outputs for compressed keys. IIRC it varies by about 10 byte (+/-) per input.
Please help how to fix this or will it be ever confirmed?
I read on other site we can respent using double spend to fix the tx fee issue is that possible?
You have two options, neither is quick.
#1 wait. blockchain.info will "return" the coins to your wallet after a few days.
#2 try a double spend. This will however not work with blockchain.info. You would need to export the private keys and import them into a different wallet. This will also need time as a double spend only works if a large number of nodes has already forgotten about the TX.
#3 Well there is a 3rd. Get in touch with a miner or mining pool and ask them nicely to include your TX with priority even though your fee is low for its size.
