OP is most likely A SCAMMER
I almost believed his story until he said this:
Lately there have been newbie accounts pretending to be asking for help, but then they start to indirectly advertise their shady websites.
As is the case for OP, he is trying to advertise his brand new(probably scam) gambling website by claiming that he won some BTC from it.
Domain information
Is it a casino?
Weird I tried to check their website but I can't seem to find their deposit page or signup page.
What I see there is a list of the casino with a category in the top left of the page.
Never heard those casinos listed from their site it is not related to crypto either.
It seems that OP owns the website but I'm not sure if the list of casinos from their site is legit.
The website is not actually a casino it looks like a portal to gambling casino or probably they just want to gain backlinks from here to their website.
How did you know that the website is a casino?
