Thank you so much guys for being awesome, four of them have been sold nicely. I'll bump this thread again if I got more key in the future. I wasn't wrong to have chosen Sythe for trades! :)
I have 4 beta keys in stock, I'll trade it around 30$ for each key. I won't go first for the trade, instead I'll give a prove that I'm the winner & have this key. You can go confirm my account on Playdota community & Steam community, I'll reply it within 3 hours.
