On 4 of your options there I will take the spot trading teaching to all newbies since this is risky options or decision that they wanna try since for sure that they would just lost their money for possible wrong decisions they take. Lots of scams or market is volatile so for sure that they will find out its hard to handle those situation and for sure that there's high chance that they would just lost on their trades.
So I would take this Learning knowledge first and Airdrop farming since this is the easiest way for them to learn and participate. But also they need to know the risk of possible scamming in airdrops so they could able to avoid those potential scam platforms.
Investing maybe I will not suggest it but still would open up a discussion to them since its important that they need to learn something about it especially for bitcoin investment for long term since this is more better decision they can take rather than participating on meme coins or hyip investments.
