I want invest more money, But i Can't find good ways. How I'll find proper ways?

You can enter the penny market if you're looking for an easy yet little amount of quick profit and it's not so risky.

Also, the best way recently is to enter the foreign exchange market and start trading with some currencies not necessary money but also in gold or crude oil or silver, etc. this is called "Forex" through which you can start by creating an online demo account (without any charges) to help you know how to be a good starter trader and if you like it you can proceed by entering the world of Forex and start earning gains. But be aware, since you must start with a small amount and see how it goes and not having the "quick rich" perspective. Patience is the key!
