Really like sites like these. Simple, homegrown sites without anything crazy.
My only criticism as a web developer for 15+ years, would be the following (and I mean this with the best intentions, btw - because I can tell how much effort you put into the site)
1. I would sway away from rotating slideshow on the homepage. Honestly, I think if you used the following image as a standard image (
https://uselessshit.co/images/card-2.jpeg) it would be much less anxiety inducing on the user. Finding a way to place the other images (if you want them) on the page, might be advisable. Remember, you're bringing new users to Bitcoin (and these foreign concepts) to the site, having a slideshow showing technical jargon right away probably isn't the best way to keep your user calmly scrolling down the page)
2. I would reduce the amount of verbiage to get to the basics. TBH and in full transparency (and quite embarrassingly) I had no clue what stacking sats was, and linking to another site (under the "were you handed a card") is probably just bad flow. I actually ended up googling it to find out what it was, vs reading the site - which is probably a bad sign. I would perhaps take the most important points you're trying to make, make them concise, and include them plainly in the first 1-2 minute read of your site. You'll get more traction this way.
Otherwise, great job! Clean design & code looks good!
But maybe it's not to late to get domain like that.
