For BTC you can use mempool.space to get estimated transaction time. I assume you're using one tracker to get the time for the different coins, so having one for just Bitcoin may complicate it, but that's the website I trust most for Bitcoin info.
Great minds thinks a like, we are using mempool and another source as a fallback, and we found the bug in our systems that caused the displaying issue so it's far more accurate now for BTC (Native & Ligthning network).
About the casinos I would not want to go into at particular one now so it would not be a direct criticism. But I feel high ratings like 4.5+ should be reserved for only elite services, but when almost all get higher than that it seems like the review site is just platforming different casinos and promoting them, this is what most review sites do by the way, so it's not a direct comment on your website.
I hear you, and it's a fair thing to raise. For context though our scores aren't handed out or anything like that. They come from our own first-hand experience (genuinely millions wagered across these platforms over the years) backed up with research, so a rating reflects real time spent on a site rather than a number pulled out of the air.
That said, you're right that any single team's perspective only goes so far, and rating inflation is a real problem across the iGaming industry. That's exactly why reworking the review system is in our dev scope: we want to layer in verifiable reviews from real players alongside our own testing, so the ratings get more accurate and less dependent on just our view.
Also, we have another exciting feature in the works, that I truly believe will be appreciated a lot, it's never been done before as far as I know on any other review sites.
