Agree with roslinpl as it's faster and the fee is so small that making it 0 and at the same time making the transactions long lasting is worthless
sure it is like this.
0.0001 is very cheap. and we need to remember that those money are needed to support miners.
I know many people who add higher fee to their transactions.
Just find any cheaper way to send money on planet earth?
(and I am not talking about other cryptocurrencies)
