How do you manage risks while investing?

I'm looking for tried and tested tips or advice on how to appropriately balance risk and reward in my investments. I've heard so much about cryptocurrencies & other types of lucrative investments, but at the same time, I don't think I could afford losing such a large percentage of my investments.

@miguelhammond10 If you can't afford to lose it, don't invest it. I learned a lot from this book: https://www.iwillteachyoutoberic.... I basically follow Ramit's advice exactly. Then as far as crypto/anything extremely risky, I only put in an amount that I'm fine with losing.

@miguelhammond10 I suggest you to choose some ;low investment and easy to success business that you don't need to be afraid of the risk while investing. I suggest you to choose some distinctive and good marketing products. I was on a business trip last month and saw a very interesting electronic product called "Unique Pocket Cinema". The waiter introduced that this was a new service product which they rented to attracted customers. It's a palm size projector, very small and delicate. I tried opened it,that's amazing, you can play it with build-in battery without plugging in power supply.You can watch movie by just connect with wifi or mobile hot spot, which is much more convenient than ordinary projector. Besides, it has a build-in sound effect,directly show on the wall, watching a large screen ultra-high definition movie, lying in bed to enjoy the hotel theater, I felt so cool ! I was instantly attracted by their projector special service. I was told that the hotel is full of customers everyday since they rented the projector. I felt that this product is so attractive that the market prospect is very good. I've heard that the suppliers are looking for distributors all around the world, you only need to invest few hundred dollars to become their distributor. Last week, i ordered a sample for test sale, and tried play movies in the square and college for 2 days. What a surprise ! I got so many customers from hotels and colleges to rent this projector and some customers want to buy from me. I'm so excited ! I already earned 5000 usd within one week.Thanks to this product for my business trip to carry out so smoothly, if you also want to do electronic products business, you can go to check their website to have a look.
