I have some Bitcoin and Litecoin wallets with very small amount of BTC/LTC in them.
I want to completely empty these wallets - send all the BTC/LTC them to another address. This address can belong to me or to the others (donation etc.).
The Bitcoin-Qt doesn't allow to send from these wallets because transaction fees are higher than the amount in the wallets. It seems that I cannot "force" this client to use smaller fees or even no fee at all.
Can I use other wallets to do this? Which ones (Electrum?)?
What alternatives do I have with with Litecoins? There seems to be only one reasonable client (Litecoin-Qt).
