I still use bitcoin core wallet which is in prune mode, not 150gb.
So there is a chanche to do it with bitcoin core then?
(always create a new backup before doing anything to your wallet.dat)I don't think this will work in prune mode. Normally I'd suggest to -zapwallettxes=1 your wallet, but you can't do a -rescan in pruned mode, so I'm pretty sure this won't work.
-zapwallettxes=<mode>
Delete all wallet transactions and only recover those parts of the
blockchain through -rescan on startup (1 = keep tx meta data e.g.
account owner and payment request information, 2 = drop tx meta
data)
