Excellent advice for the new crypto investor. I especially like the idea of starting out small and doing an end to end test; making sure that your wallet has connections, that your crypto exchange of choice can successfully receive and deliver your coin, and that in the end, you are able to test successfully converting it into cash. If I had run this test from the beginning of my investment career, it could have saved me a lot of trouble and taught me a lot in the process!
