Again, I'm looking for solid pieces of evidence (not "I've been scammed", "they did this and that", "my friend was scammed"), even though I realize how much the cases of your friends matter to you.

I definitely acknowledge that 1xBit did not act perfectly in the past. It's difficult to say the opposite considering all the bad reviews on BitcoinTalk. And maybe have they not made the efforts to resolve these "old" cases properly, which is definitely not great behavior, too.

But as I mentioned, I didn't find so many scam accusations recently (2019 and 2020) during my searches. This is why I'm looking for recent pieces of evidence that 1xBit is not a fair site to play on.

Also, 1xBet is different from 1xBit, aren't they? Even though some people say the management is the same. I'd also like to know where you get that from.

Note that Trustpilot isn't a trustworthy source of reviews. It's easy to buy thousands of great reviews for your company and terrible reviews for your competitors. Just check this example. https://fr.trustpilot.com/review/skrill.com
Skrill is rated "excellent" while they provide really, really bad service. All the great reviews are very simple and often not written with proper English.
