thanks for replying
but i need to pay in cash, so how else could i do it if paying in cash?
There really is no other ways to buy Bitcoins in cash. You should just put the money in your bank account and buy Bitcoins with paypal.
there's still a way, meet local exchanger and ask them to have a meeting with you, i can sure they will not going to refuse if the amount of transaction is quite big
This is exactly the best way, but I feel you need to find the right trader. You need to meet him at his place or go upon his suggestion.
