Going a little broad here, but here are some other thoughts worth keeping in mind as you jump into the space:

1. DCA can be boiled down to splitting your one-time large investment into smaller increments over a longer period of time. However removing the investors emotions from the equation is where DCA really shines…meaning set up regular purchases of say a couple hundred dollars of X crypto every week or so, until you’ve hit your investment limit. The frequency and amounts tailor to your own situation of course.

2. Boring, and most YOLO redditors will laugh at me but I highly recommend starting your crypto journey with a habit of record keeping. For example, document every purchase, the amount, date, number of coins, etc. This will not only help you see your project grow and give you insight into your DCA (see above), but will help with long term vs short term capital gains tax considerations.

3. Why do short term vs long term capital gains taxes matter? Because there’s nothing wrong with taking profits along the way to new market highs. The HODL gang will scoff of course, but to each their own. Your crypto spreadsheet (above) will help you calculate the long term gains if and when it’s profitable to take some off the table.

4. Lastly, consider diversifying at some point. Not saying diversify your 10k amount, but if you continue to invest in the market it would be wise to balance the expected return vs. volatility. In this case, ETH like BTC are relatively low risk crypto assets (still volatile compared to more traditional markets). Therefore, having just ETH in your portfolio may be relatively “safe” for crypto. It’s the second largest blockchain by market cap after all. But there are other, smaller, alt coins that offer potentially larger returns at the risk of greater volatility. I won’t name some here at the risk of being a shill, but go to any exchange and pull up the top 50 coins and start doing some research.

Cheers, and have fun!
