Alternatively to be on safer side why not start trading with cross margin with a leverage of 3X which is less risky rather than future trading, I tried future trading got a margin call unfortunately got liquidated swiftly due to high volatility in the price of the pair traded thereafter I switched over to less risky option, trading with less risky option and earn small profits is better than trading with highly risky option like future trade in a bid to earn huge profits but ended up liquidated, you have to erase the mindset of becoming rich quickly in trading, earn your small profit while compounding it will amount to huge sum of money in a long run.
I would say if you really want to stay on the safe side, then just do not trade with futures at all. Spot trading is a lot more safe and secure, that way it wouldn't be possible to get liquidated and unless you invested into LUNA or FTX then you wouldn't be losing all of your money, there would be some drops but those will be just a small loss whereas in futures trading you could lose 100% of your money.
This is why I highly suggest people to stay away from them unless they know what they are doing. Yes, it’s true that some veteran traders could turn a few hundred dollars into tens of thousands of dollars with just a few trades there, but that’s because they are veterans and know what they are doing.
That is one option that’s true, but if people really want to trade on futures, they should at least know what they are doing. You can warn people as much as you can, but if they set their mind on trading with futures, they will do that. At that point it is better to point out what the common mistakes are, and hope that they won't make the same ones.
Simple things like put a stop loss, so you don't get liquidated quickly, or doing your TA carefully before you start, or not putting all of your money into a single trade, or not to make the margin too thin with huge amount and high leverage. These are all common mistakes that people still do to this day.
