People will tell you to delegate, stake, deposit in exchanges to earn interest and easy money from them. I won't object but what I'd like to tell you is before you do any of them, you have to know the risk that they have. The risk is you're giving them the whole trust of your fund and whatever happens to them, they might reject to refund your money, that's it.
If you don't have the skills then real estate is the best option to go for it will give you some good profits.
I agree to this. Owning a real estate will have you two things or maybe three but here's the gist;
1. Yearly appreciation of the real estate value. So, that's still passive income and it's to be the known one of the best assets in the world.
2. You can have passive income through renting it.
3. You can pass it on to your kids or whoever as an inheritance.
