Apparently, there are only two possible things you can do to have a passive income -- ways that your money would work for you. It's either you

• Invest in crypto -- which would have a lesser risk as some popular cryptos nowadays do have strong volume and support, but still DYOR before engaging with it. Investing would still not be a huge income generator as it would depend on the growth of the crypto you've invested on.
• Copy-trade -- which would somehow require KYC like in E-toro but is beneficial for long term passive income. Same as with investing, but this is investing on the capability of the trader you are copying. If he is bad and just burning his money, you'll end up being the same.
• Mutual-funds -- this is the safest, as it relies in Stock Market (usually) and how strong a company you are investing your funds is. Risky, but not as risky as crypto.

Overall, it would still depend on you're choices and risk appetite on which risks you think you can handle.
