for Fiat currency conversion of bitcoin i use localbitcoin as i am from india so coinbase dont support india, but in localbitcoins i get so many users who are from india and are buying in the market rate with direct payment to my bank.
I wish I can find people around where I'm from to buy Bitcoins from... I've tried to use localbitcoin, but sellers are so far away from where I'm located that it's impossible to set up a transaction, not to mention that Bitcoin ATM's are even farther away. AND I'm from the US, which is pretty sad to say lol... think it's time to move to a bigger city
