@AyanB214,
The Ads system uses machine learning to determine the ads most relevant to you. So part of this is dependent on your browsing habits and how long you’ve “trained” the system to know what you consider “relevant”.
Another part of the equation is what ads are available to show you at all. Ad campaigns vary by region in both number and types of ads shown (note that you can see what ads/campaigns are available in your region here). So the fact that you are seeing crypto ads means that you visit enough sites related to “technology” and/or crypto for the system to feel like they are relevant to you.
If you’re only seeing crypto ads, it could mean:
- In your region, there are only crypto related ads/campaigns running at this time
- You browsing habits are such that you don’t meet the criteria for other types of ads that are/may be running in your region at this time.
There are other possibilities and factors that could be at play here, but those are the major considerations. If you want a deeper dive into how the ads system works, I recommend the following article:
