they just wanna scam you. most of these new sites come up with ways to scam players.
i have learnt my lessons and now stick to old sites
It's not that simple. A site regardless of its age can scam you and examples like 1xbit + 1xbet can attest to that. BC.Game don't scam players outright, but they resort to unethical tactics on a regular basis in order to avoid paying.
This is why it's best to stick to reliable and trustworthy sites like Stake etc that don't resort to such tactics if you ask me.
