I really have the same problem,

BitCore wallet is stuck with a transaction with low fees and my option for change fees was not selected so I am kinda screwed ....

all my other transactions are stuck behind the 1st one...

I tried viabtc and also asked f2pool admin to push the transaction .... and then I am still waiting ...


It is very hard to find when the transaction will be forgotten by the network ... It is supposed to be 72 hr but it's already more then that and my transaction still there ..

the other option would be to do a double spent but I have no experience with that and I am really not sure about the procedure.

looks like I have to run bitcore offline then spend again the same amount but not too sure about that and how the network will reach.

Anyone can help me on that ..

it would be really appreciated

thanks
