Thanks for the update! I'm a total noob compared to you haejin. But i'm running a portfolio experiment that could be interesting to you. The experiment is based around the question: What will happen if I invest a 1000$ in each top 100 coins based on market cap.
I've build 7 portfolios a top 100,50,25,10, 5 and 2 others to compare with each other.
anyway the full explanation and updates are here: https://steemit.com/cryptocurrency/@armtrack/the-experiment-explained
