I dont think feeless transactions are possible but cheap and fast transactions is definitely required for adoption.
It's possible dude and there some platforms that already created feeless blockchain to give the advantage for the users to send zero fees transaction
Fast tx is really needed to develop the blockchain game, dapps and various things. Any activities on the blockchain will always be related to the peer to peer transaction.
That will bring more adoption.
i'm exited to heard about the zero fees on transatcions and thats will be a great my friend
and we have a same view, if feeless or even zero fees on transactions will bring more even mass adoptions mate
