Like the topic says I have unconfirmed transaction and I just can't wait for it to transfer anymore. So is it safe to make another transfer while I have that old still in the loop? My wallet is Multibit 0.5.15 and I'm afraid of upgrading it while this unconfirmed transfer hasn't arrived because I don't want to get in to any more trouble than I already am. Does it matter which wallet do you have if your transferfee is correct?
If you make another transaction (spending the unconfirmed outputs) it won't get confirmed until either the first transaction is confirmed.An exception is a Child-pays-for-parent transaction which spends the unconfirmed outputs from the pending transaction but with a high-enough fee that past for both transactions so they both get confirmed together.
I'm not familiar with Multibit so I can't tell you how to make a CPFP transaction with it.
