This is the reason that I always cash out my bitcoins in a different account than my usual account which I use regularly so as to keep track of the money that I have made in INR with bitcoins, if it goes above the non taxable limit then I pay whatever the tax applies so as to not get into any legal trouble, as getting into a legal trouble like tax issue will hamper my reputation in my community which I respect the most even more than the money I make as money can be earned again, but if reputation get tarnished then it's pretty hard to earn it back.
