First off, your site is very neat, navigable, and has everything I need from a Lightning explorer. I tested this with the Bitrefill Lightning node, and the information seems nearly correct except for the issue that things aren't being analyzed in real time, which is a minor drawback compared to everything else on the site. I typically don't use Geolocation for nodes, but it's something neat to look at. Good touch!

Second, what sources do you use to calculate the fiat pricing of coins? You don't have anything like a FAQ on the site that explains this, and this is something typically listed on most block explorers. It's always interesting to me and also somewhat important that sites use a reputable source to base prices off of.
