Kindly consult your CA before you start dealing in btc with such a huge amount. There is still not much clarity about btc and government my decide to either bring stringent laws or may ban it. So better be cautious as in some time we will hear it soon. Think before you start trading with your 20 lacs approx daily.
I have already started doing it , and all CA hve just question mark on their face when i show this case!! So not much helping me about it . Ill just pay ITR for now
