Like a twat, I tried to deposit 4 days ago with too low a fee and now something has gone wrong; my coins are stuck between my multibit wallet and my dream wallet.
Is there any way I will get my coins back (or better yet they actually go into my dream wallet) so that I can resend with a higher fee?
As far as I know, you just have to wait it out. For next time, you can enable dynamic fees and RBF if you use the newest version of Electrum (or another wallet that supports it). That way you can bump the fee if they are stuck. For now you just have to wait it out, sorry bud. Just don't send anymore coins. It will fall out in a couple of days.
