This is my BTC address 1JAzCquFwPQG7Ko7Bjz8HpJGQb6kkVnRyT
you've imported wrong private key. let me guess it starts with with K or L
bc.info gave you private key for compressed address while yours (1JAzCquFw) is uncompressed address
check my post here https://bitcointalksearch.org/topic/m.26729170
read the instruction on part "acquiring your privkey" , the other instructions are irrelevant to you
just a little note, download bitaddress tool from github and run it offline for your own safety
after you get the private key that starts with a 5... then you can import it into your electrum
if you still have problems after importing, don't hesitate to ask again
now I understand. Perfect I succeeded, thank you.
Now, in your opinion, is it better to accelerate the transaction at a paid accelerator or with double spent?
I would not like to pay a lot for the transaction, but only to unlock the transaction with little ammount! It's possible?
