A coin not having a transaction fee could immensely help the problem of scaling. If the transaction output capabilities are big enough and the security concept proves right, it could mean a new solution to the crypto scaling issues we see with POW coins.

It almost looks as if another solution to scaling cryptocurrencies is presented each day. I hope these solutions prove solid after testing and trying, so that it can either find its way into Bitcoin or a new runner up coin.

Diversification still seems to be key now.
