Correct answer.. His question was also answered on a separate thread he created - https://www.cointalk.com/threads/can-someone-tell-me-about-this-dime.314710/
OP didn't like the answer in the other thread. So, somehow, thought he would get a different answer from the same crowd ... Guess he's still stuck on STEP 6 https://www.cointalk.com/threads/can-someone-tell-me-about-this-dime.314710/#post-3053378
