Here are some recommendations for products I use and I really like. I hope they can be of use to some of you as well.
There are not a lot of things you need for your investing. You will mainly need a broker. For this, I recommend Interactive Brokers. You will also need to decide what to invest in. I have more information for you in my Investing Recommendations page.
If you are serious about investing, you will probably want to read some books about it. You can learn a lot about investing by reading books. I have read many books about investing, personal finance and even minimalism. You can find all my reviews on my Book Recommendations page.
I think that credit cards are a powerful tool. They allow you to get some money back on your purchases. Of course, you always have to pay the balance in full. Otherwise, you are asking for trouble! And you should be aware of the hidden costs such as foreign currency exchange. I personally use the Cumulus Mastercard and the Revolut debit card for my foreign purchases. You can read more about my credit card strategy if you want.
