i cant put my hydras for sale, this keys is bit old, why its not on the site yet?

i can create a trade on outspot selling stuff for money(that are not on my inventory) and leave the link to my shop on marketplace.tf?
eg i'm selling my an unusual for money, but the unusual is on my shop on marketplace.tf and not on my invetonry.

bitcoin is becoming more and more popular. Steam is already accepting bitcoin. So why not outpost too? c:

This has already been suggested and this is in response. if you look at #4 they have answered. Hope this helps!

I'm not talking about a donating system.
I'm talking about premium.
They not the same thing.
Example:
http://backpack.tf/donate
http://backpack.tf/premium/subscribe

I'm a trader who is not spending real money and i prefer items as a payment method, i think i'm not the only one who want keys as payment method for outpost's premium :|
Also, i'm brazilian and we brazilians cant receive personal payments on paypal, it means if i sell keys for money, i'll lose $0.30 + 6% for each sale, what make the outpost's premium be really expensive to me.
backpack.tf selling the premium for 3keys/month and 5keys/2 months

outpost is not loading my csgo inv( http://imgur.com/c3Z0PQi ) , its not a new problem.
backpack.tf is loading my csgo inv and outpost is not, the problem is not steam, cuz backpack.tf is loading my inv inv and outpost still is loading my tf2 bp.
and a staff closed my trade( tf2outpost.com/trade/28122563 ) cuz i dont own the some specfic keys.
And now i can't sell my csgo keys on outpost, cuz outpost is not loading my csgo inv and i can't create a new trade with my csgo keys, and thats why i don't create a new trade when i sold the keys here tf2outpost.com/trade/28122563 , cuz if i need to sell my csgo keys and i can't create a new trade to sell my csgo keys, why i'll close the old?
On my trade i was saying i'm selling ANY of my csgo case keys and buying ANY csgo case key, like a tf2 keys/tod banking. Could re-open my trade? :/
