My friend is a long term investor but wants to become a trader

no the return calucation 15% *2 = 45% is wrong. It should be 30 % not 45% but rest was correct only. I explained it based on below

I removed everything as people were getting confused.

But I do agree with @SpacemanSpiff and others reality can be very different , no one can project returns. I am just saying 1cr return may or may not be possible
