Good day as I am new to the crypto world What is really the way to make $ in in crypto ? such as Bitcoin or other coins?

I understand as i have some invested. in my wallets the values go up and down, so you can cash out or sell when value up?

do you just buy and sell currency as the markets move up and down? or what other ways to make $ with crypto?
do you transfer bitcoin over to other websites etc?

or what should i be focusing on? thanks

just like to know what all the experts do?

Well to make money in cryptoone of the best is Bitcoin Faucets
A Bitcoin faucet is a type of website that gives away small amounts of Bitcoin to its users, with owners making money by placing ads on their website and pay individuals who visit the ads or complete surveys. This industry amounts of over 50% of the traffic on leading Bitcoin websites today. Faucets let visitors earn a percentage of the Bitcoin that they give away to any visitors that you brought in. This has resulted in users using a Bitcoin faucet rotator that allows users to quickly surf different faucets and earn a commission through rotation links for each faucet visited by you. However, similar to PTC websites, Bitcoin faucets are not a realistic way to earn good money, with even the best faucet rotators being applied still only enabling users to make no more than $1-2 per day.
