Hi, I would use dollar cost averaging across several buys to establish my position in a particular coin. Then I would set a target % allocation for each coin and that’s going to be the target % of ownership of each particular coin in your portfolio. Then, I would use re-balancing as a systematic approach to buying low and selling high. Re-balancing is critical to helping you keep emotion out of your trading. You want a plan and then you want to execute on that plan.

An example of rebalancing — say I have a portfolio of BTC, ETH, EOS and NEO, all with target percentages of 25% (to keep the example simple). Say EOS really takes off and my portfolio now looks like this: 20% BTC, 25% ETH, 35% EOS and 20% NEO. Looking at today’s values per coin, I would want to sell some EOS (because it’s over the 25% target percentage) and buy some BTC and NEO (because they are under their target percentage of 25%) to get back to my target allocation percentages. You can do rebalancing daily, weekly, monthly or quarterly.

You can use CoinTracking (https://cointracking.info) to help manage your crypto portfolio.

And this article I wrote also can apply to crypto-investing: https://hackernoon.com/four-important-tactics-to-investing-d0f2845b4f4a
