Hello,
I read many things about transfees(not be included in a block)
Any I saw many transactions without fees and still getting confirmed.
How is that possible and how can I actually do it?
i found out that it is possible to send a transaction without any fees but in fact changing the fees depend on your wallet!
my experience is if you are using blockchain.info you can easily change it to zero and send it if it is not confirmed within 2 days it will be rebroadcasted automatically until it gets confirmed.
if you are using Multibit or Electrum the only way to change the fee is to change the coding and compile the wallet again!
Multibit doesn't allow you to change the fees. Trying to coding and compiling the wallet yourself, can complicate things and is not recommended.
