Where to start as a complete beginner?

I've started to get interested in crypto and trading recently. Im finding that there is so much info out there that I can't really figure out where to begin. I'm interested in making some long term investments but I'm also in interested learning more about trading too. Would you recommend using an app like Etoro to practice with a demo account or do you know of any similar apps? It was initially the Learn section on Revolut that got me interested so I think it's a more in indebt version of that that I'm looking for. Or pretty much any recommendations on where to get reliable, easy to digest information would be appreciated.
