As mentioned below here, I would advise anyone to participate in staking, airdrops on exchanges, or launchpools instead of trading. However, if they insist on trading, it's better to start with spot trading instead of futures.
Staking, airdrops, and launchpads aren't worth one's time. However, if someone has huge amount of money then surely they can make profit from staking and launchpads or from those airdropped coins.
Those who hold less money should always consider trading as that's the best way to make money from exchanges I believe. I'm pretty sure that you've lost money in trading that's why you're trying to stop others from trading.
Trading surely isn't for weak hands, it's for those people who can control their emotions and make trades by doing research and with a good strategy. Those who are making money from trading will always recommend it. One should definitely ignore futures trading.
