I know that this is not an answer to your question, but you mentioned you are using coinbase, and just friendly advice, if you haven't, please look into hardware wallets. Especially if you are really planing on a 5 year investment. There are great topics on this forum that get more into it so check that out, it will save you a lot of headaches in the future.
I appreciate the heads up. I am experiencing information overload (in a good way) finding this forum and the digital wallet is one of the main things I want to research before I invest much more into crypto. I joined Coinbase because it was easy and I wanted to test the waters to see how the crypto market worked. Now I'm totally obsessed, it makes traditional investing feel archaic.
