Andreas aantonopoulous has some great older videos. I think this would be a great starting point.

Also his book the internet of money is great.

Personally, I would say use well known exchange operating in your country. Get well known brand hardware wallet. Dont invent your own stuff and use hardware wallet as adviced by manufacturer.

Obviously depends on how much money you want to secure.
