If you didn't have it in your balance at that rather shiny numbered block (it was around 20th of june if i remember correctly) then it's not in your blurt balance. Sorry you didn't hear about it.
Certain people didn't want this project to happen so they didn't make it easy for us to reach our fellow users. That block was exactly the one before the infamous HF23 fork that robbed certain other users. We don't rob people, but we can't be everywhere at once.
It's taken quite some time for steem, and also hive, users to learn they have an account here.
I don't think that's gonna be the case for much longer though. Good things are coming.
PS: look at the sidebar, top right of the page, it lists all venues for trading Blurt.
Thanks. I see it was added to hive-engine.
