Sorry for neglecting the thread.
They are humble bundle keys right..
I honestly have no idea, but I'm pretty sure 97% of them work.
You don't know what games You can get from this CD keys?
How much of them You have?
What is the price for all?
Did You try G2a com?
You can sell them there easy using RANDOM CD KEY sell offer and propably You will be able to cash out in BTC as well ( not sure at all )
Escrow?
Maybe I'll sell them on G2A instead, but I'm in need of BTC right now.
And yes, escrow.
If one of those CD key contain cs:go cd key than i will be happy to pay 0.50$ to you. Or if it is for any shooting games i want to buy but quite confused that how you don't know what those cd key are of if you have bought it from somewhere before
