I am located in Delhi. I am involved in mining of BTC and Ether. I want to sell 25 BTC and 100 Ethers, but all in cash. Interested People please post here.
Well if you really have that much amount I would be really cautious when dealing in cash or in public. One gun pointed at you and you will walk home empty handed. Its better you don't disclose your public information or the amount of BTC you have as it is sure to attract a lot of Thugs.
And for the exchange I believe you should find someone on localbitcoins.com. IIRC I have seen listings for exchange in cash in and around Delhi. Or if you find someone trustworthy then no harm in traveling to another state to get a deal sorted. All the best!
