Nobody will (or should) give 2 BTC to a newbie on the forum without using Escrow. Without a vouch or offering to use escrow you will not find a buyer I am afraid.
Sorry I can't use Escrow or send my item for vouch, because this item cost 2 BTC.
This must really be an aggressive marketing approach because the op does not give out vouch copy, he does not accepts escrow and probably does not send the product first.
I doubt a dark trust member can sell their product in this manner should they wish to sell any product how much more a brand new account.
In addition you dont win money or those marketplaces but earn money.
Good luck with your sales.
Ok, I understand, the buyer must trust me to finish this deal... I don't see another way, this is like a gambling and a poker game, maybe this offer is a scam and you will lose 2 BTC, and maybe it is a legal deal and you will be rich after few months.
Anyway I don't care, you will not deserve this opportunity if you are afraid and hesitant.
