Blockchain.info have online wallets but you can also just create your own transactions without using their wallet.  Add an address using import and then spend them directly using your private key.

@fredsbend well at the very least i know a can do an import if i run a full node of each coin, so I'd rather do that for btc than pay the fee!

@fredsbend yeah i would only do it fot btc. Its only about 0.05 Btc but over a handful of different addresses so it will soon add up. And it's the principle dammit! :)

I used multibit years ago - now what? (BTC, BTG, BCC etc...)

I have some old wallets from multibit era (~2013). There is no way I can now download the full blockchain, so I need to import these keys into somewhere. Worse still, I also need to import the same keys for BCC and BTG.

Try as I might, I can't seem to find clients that allow me to import old base58 keys. I have a few files called `something.key` which came from multibit and are human readable with the private key in. Everything seems to be "mobile" and "QR codes", "passphrases" and whatnot.

It's not a lot of money, and fragmented over multiple wallets, so with transaction costs stupidly high now, sweeping is infeasible.

How can I spend these old coins? Is the only way to free up 150GB and wait?
