Why do people still send transactions with no fee? It's such a tiny amount of money, is it really worth the stress & worry, waiting for confirmations that might not even come.
Just pay the fee people, stop jamming up the network with junk.
because they can. last time I did it simply on purpose to get some real experience, how to do it and how long it takes:

btw, I have to wait ~33 hours, which is not so bad at all, but it just depends on luck, there is no accurate reply to OP question..
