My strategy of portfolio management has changed drastically from year to year. 2017 trends made me invest in ICO too which I can't even think of now. I had a diverse portfolio from Bitcoin to low cap to ico tokens. But 2018 I completely shifted to bitcoin. I was holding no altcoin and that saved me from a lot of bloodbath. In 2019, I started buying a few large cap altcoins in the second half of the year. But still Bitcoin dominated the portfolio. This year , I am kind a bullish for altcoins. Would be diversifying my portfolio if I could catch a good entry point.
