What is the best online wallet without any tax / fees.
Except for blockchain
BitGo.com is keep charging me to pay the miners
if you want, you can do it with wallet-QT too..
but if you set 0 transaction fee,
you have an high risk to get unconfirmet transaction!!!
and until the transactio remain unconfirmed, your btc are unavailable!!!
in addition to, you cannot delete the transaction.. so you can just to wait until the transaction become abandoned.
The transaction then disappears from blockchain.info/wallet as if it had never been made.
Now you can use your btc again.
