Thats true. It will be futile to spend huge money for promotion if the reputation of the site is not good. Because gamblers are wise now to not risk their money on a shady site.
It's not that simple. 1xbit advertise their services across different platforms which is why they are still somehow attracting gamblers despite all the rising negative accusations against them over time.
Their bad reputation in Bitcointalk has definitely affected their business, but it isn't enough to shut it down completely.
Unfortunately you're right. People who dont know this forum and lazy to make a research about the reputation of this site are likely the ones to fall into playing for not being aware. The fact that this casino is still existing despite of the unresolved issues just shows their marketing strategy to promote their site in different platforms are still effective. Because it can attract naive gamblers or should I say the newbies who can be easily convince.
