Hello I am using an old BitCoin client named MultiBit v.0.5.18. There is no option to change a fee. My transactions that I was send two days ago still in 'Unconfirmed status' and I guess here is a problem because I cannot move money from this wallet and may will never can do it.
The wallet set the default fee to 44.843 sat/B. It is lower for current time. I see the middle fee is 220 sat/b for now from https://bitcoinfees.21.co/.
How can I solve the problem? Is it possible to open wallet through another client? Electrum for example. Or I should wait when fees will go down (if not?).
