Thanks! Isn't Bitcoin and Etherum different in how they function on the blockchain though?
You asked for advice, so just listen
There are a variety of ways, because there are a variety of blockchain. But to understand from the beginning, you should go through the basic "education" material, which is generally based on Bitcoin. And once you know Bitcoin, you will find it easier to learn something else. Also, there are other types of crypto that don't use blockchain but then that is another lesson for another day.
