As above..

- You don't have control of the receiving wallet, so CPFP is not an option.
- I don't believe that b.info provides any RBF facility
- Fee was 65 sats/byte... so ViaBTC is an option, but VERY difficult to get in these days... I am about 99% convinced that the AntPool accelerator no longer works (most likely due to abuse )
- I believe b.info does enable you to export private keys (or at least has a recovery seed which you can use to get private keys), so exporting and importing into another wallet that would allow you to create a double spend is a possibility.

HCP thanks for the reply - could you possibly provide a link I could read that could help me figure out how to do this process? I'm admittedly a little slow on the technical side of creating these transactions...

Hi Mocacinno -

Thanks for creating this help thread! I'm also experiencing difficulties, though I fully accept they're a result of my own lack of understanding of the current transaction climate... I hope I've appropriately listed everything.

transaction id: 3471bffae48a22a14d7791a24aa95a992b44116179cd7ad9e1b0c502fa6f26c7
sender/receiver: both
addresses:  12khGTi51tRpK4xNYuaxCyK4qEZ5FoiA75 is the sending address, 33QGRwsykMm6UAHNjjvG3YU5JNNe6tMZdg is the receiving address
wallet software: sending wallet is blockchain.info, receiving end is a kraken exchange account
mempool: yes, i have checked http://www.mocacinno.com/page/getraw, entered my transaction id, and i was shown the raw transaction, so this transaction is in your mempool
something strange: no, i have checked for unconfirmed parents, dust outputs and double spends on blockchain.info, and could not find any anomalies
rectified situation: yes, in the future i'll use dynamic fees, and set the slider all the way to the right AND i'll use http://www.mocacinno.com/page/feeestimate for a second opinion
tip: My bits are all tied up in this transaction, but if you're able to help I will gladly send a tip after the tx goes through!

Thanks for any help you can provide!
