You can go on settings and change the transaction fees.
However, it's better to pay a few cents than to have your btc unconfirmed.
It might take longer to be sent and your btc might be lost in the way.
I think the risks are a bit high, especially if you are sending large amounts of btc.
Can someone teach me how to send with 0BTC fee from a bitcoinqt or blockain or whatever else exept coinbase (coinbase is already free). Is the only way to do that is to create a raw transaction if so how give examples i think lots of people are interested to know how to send with 0BTC fee.
Bitcoin-QT: Settings > Options [Main] "Pay Transaction Fee" adjusted how you want.
Feel free to test it out, my address is 1Hdn5TE9jxMMY1dBwn44y8LFxZw6xN5kPi
I tried it on bitcoinqt and it didn't worked it sayd that minimum transaction fee is 10ksat.
