If you are definitely not going to travel, then the option of exchanging them for money does sound reasonable. But sometimes you can use them in other ways. For example, some airlines and banks allow you to pay for car rentals, hotels, or even gift cards with miles. This can be convenient if you don't want to deal with selling. On the other hand, exchanging miles for cash is often more profitable because you get real money that you can spend anywhere. Here it's a question of priorities: either comfort and ease of use of bonuses, or maximum financial benefit. I would advise comparing different options and choosing what is closer to you. The main thing is not to leave miles idle, they really do lose their value over time.

Most people do not even realize that airline miles and credit points are real financial assets. They really lose value if they just lie around idle. You can easily convert loyalty points to money through The Miles Market service. This is the most reliable mileage broker in the world, they have over 50,000 satisfied customers and excellent reviews on TrustPilot. The process is very simple: you indicate how many miles or points you want to sell, receive an offer, agree - and the money comes immediately. I used this method myself and was able to literally sell airline miles for cash and even turn credit card points into money without any risks. The money was transferred within 24 hours, everything is safe and transparent. I recommend trying it if you do not plan to use miles for travel. It is much more profitable than just waiting for them to depreciate.
