I agree with most of the portfolio. Except Etherum. I do not have faith in the security of eth. It's amazing to me how it's value continues to go up despite it's flaws. I also think if you have less than a Bitcoin in total value 15 altcoins is stretched a bit thin. I learned this lesson during September and October when my 1.8 Bitcoin portfolio value went down to .70 Bitcoin value. So while bitcoin was running wild my portfolio was going down. I wish I hadn't spread my self so thin before. I would be sitting pretty. Most of these altcoins won't be around in a few years so HODLing is extra risky when it come to altcoins. So my goal is to build the amount of bitcoin I have. I already bought back into bitcoin on the initial dip. So my fiat stash is gone. I sell on the way up. A little here a little there building my fiat stash. To buy back on dips. The good news is my portfolio is up to 1.5 Bitcoin and rising. Everyone needs to assess there own risk tolerance and act accordingly. Thanks to you Haejin I have better recognition of the trends and do my own analysis.
