1. Bank deposit is just an assurance/backup plan as you still have money in case all of other investments failed. Don't think your money will grow bigger as the inflation is growing as well, it can be 1-1 = equal
2-3. I won't recommend investing in lending and mining, it's better to hold your bitcoin/free money and allocate to other choices.
4. The same thing applied for the reason 1, the gold asset is just an assurance/backup plan.
5. Buy a property can be profitable as long as you make it productive to generate money, even buy a land is profitable for a long term.
6. Other ideas, create your own business (sell something or offer services) I can't tell the right business for everyone as there are a lot of factors affect it, such as your talent, interest, hobby, capital to start, where do you live, and so on.
I will go for 1. 4. 5. 6.
