Thanks for your reply.
Buying @ Bitfinex for $920 / BTC is wise choice, b'coz Coinsecure price is $1000+
Is it bad to use international exchange?
The big question here is, how do you fund your Bitfinex account with $920 ?
If you are thinking of sending $920 to Bitfinex from your Indian Bank Account what are the costs associated with it ? What exchange rate you get ? How much time the fund transfer takes ?
What are the legal obligation involved in outward remittance from India?
The problem that they might currently face is, many exchanges have stopped considering Indians to be allowed to even sign up and open an account there, and if they can, they are still restricted from trading or buying/selling bitcoins on such exchanges because of inflated rates in India. I don't understand the exact reason behind it whether it is the high price only or is there something else that we don't know?
One more thing you can consider of buying is through LOCALBITCOINS.com site their also you can get cheaper then coinsecure and their you can buy with indian currency so even if you trade between localbitcoins and coinsecure you can nicely earn the difference rate benefit.
