Steem has the fastest transaction time, and are working quite hard to launch the SMT which will put more business on the Steem blockchain thereby increasing its network size.
Yeah i agree
But converting steem to another currency attracts charges..but its still okay.
But right now, it doesnt attract charges so lets enjoy the benefit
That's not a feature that is cause by Steem, it is cause by your exchange. So they are the ones who determine how much to charge for using their services.
I think it is the same with almost all coins.
