How much daily visitors do you have? I haven't checked anything but with low number of visitors, it's very much unlikely that you will get a good revenue from any methods you use.
However, from my personal experience, I would recommend you to affiliate for an exchange which can be a good one in future. I have tried Binance and Kucoin for a long time but got no good return. Got 1 sign up only.
Besides run adsense though it won't get you a good revenue unless you have a huge visitors though CPC depends on country base. In my case, I barely got $0.03 even lol.
You can also reach out to new crypto start up for a custom deal like selling a banner space. This is one of the best methods I think as the success rate could be higher if you can present professionally.
The best way to monetize a website is through affiliate marketing and selling services to your visitors.
As easy as it sounds, maybe as hard as it is. It's not that easy to sell services. I have been trying to sell one for the last year, I wasn't able to get one single deal lol. Maybe I'm doing things wrong but still, it's hard. You also should know that OPs site is in local language.
