pacer Anyone have any knowledge of this stuff?
Most of my investments are in the stock market, mostly tech stocks because that's where my experise is. But, like you, I became very interested in cryptocurrencies when my friends couldn't stop talking about them.
I installed Coinbase, which has a very good reputation, and I've been very happy with it. Check out coinbase.com. It's not available as an app in the repo, but it's an html application, so you install it into your favorite browser. As an experiment, I bought just a few thousand dollars of three currencies - Bitcoin (BTC), Ethereum (ETH), and a little less of Dogecoin (DOGE). I bought that last one because Elon Musk is a big fan of it. (Dogecoins were $0.08 each when I started this a few months ago, and today they're $0.18.)
Coinbase has made it easy for me to learn a lot in a brief time. Highly recommended, If you're not ready to actually install something right now, just do a web search for Coinbase.
