In any case, it is not a large site, nor a site with a large or good reputation. You should always be careful with such sites. I don't think you can draw a conclusion based on the layout. There are of course other gambling sites that have a layout similar to this site, but that is no reason to give an opinion. You have to look into the content of any complaints. Unfortunately, there are quite a few complaints about this gambling site on the internet.
Not quite a few but most of the feedback about 1xbit is negative. 1xbit is a scam site and it has been initiated many times here on this thread and on the forum. They will eat up your deposit and will never give you your money back. Strangely they will only pay their signature participants and you will only find their signature wearing participants promoting them.
