What does it means just writing buy BTC? Can you be more elaborate and mention all the details as against what you are buying is it against INR bank transfer , Cash, Alt coin ? What is the rate you looking at is it Preev Price or Preev + 2% etc?

It is better to mention what are the rates? what kind of payments acceptable? If in cash then area of country-city etc. Be more elaborative. otherwise people will ignore your offer as spam.

Are you trading on bitcoin exchanges ? there are some good exchanges like coinsecure, unocoin, bitxoxo etc?
