In China, Hong Kong, Japan, etc., there are many buyers who want to buy more than 10k BTCs to find me to act as an intermediary.
But there are not many sellers on this side. Is there any way to find more real sellers?
The problem here is that you are a newbie, how can we take your word seriously? Buying huge amount of bitcoins here involves trust specially on the part of seller and you don't have one. You said you have made a few good deals here but all I see in your post is all about bounty?
