No I am not gambler, I am crypto marketer, doing marketing for shitcoins , and remember when I checked BCT before it was about ICO, Bitcoin and marketing, now it like a total casino advertising platform.
The forum is still about Bitcoin, you just need to visit specific sections for each piece of information. "Show unread posts since last visit" shows you a mixture of posts from all the sections, so you can't judge the forum only based on that. There is no doubt that there are a lot of casinos that are promoted and are present in the forum, but factually, since all those casinos have Bitcoin and other cryptocurrencies as their main payment methods, they are technically related to Bitcoin, so they have a reason to be in this forum.
On a different note, I would rather gamble my money away than invest them in a shit coin or an ICO.

Or, we could say that investing in these two is nothing less than gambling in itself. Anyway, I believe the forum is better with casinos and gambling than it was with ICOs and shitcoins back in the day that used to scam people most of the time.
