Some time ago I had some tokens in a old wallet and didn't had the BTC 0.0005 required to do transactions with Counterwallet. So I just used FreeWallet to do the transaction with a fee of 0.0001 and it worked;
Of course... I didn't think of sweeping! Thanks for that! It'll probably make sense to do it once I have those several addresses of about 0.0005 each. Again, it's not so much the money - even if it may end up being worth more than a few dollars. Just don't like the idea of gathering dust. Makes me wonder how much bitcoin is left languishing on wallets with miniscule amounts.
