Based on my personal experience, Stake is a legit platform because I have spent some time shifting from btc to eth. Their license is 100% in order, and seeing as their focus on crypto payments makes transactions incredibly fast and secure, I think its safe to say I am in the positive. It often took just a few minutes, but the deposits and withdrawals I made with Bitcoin and Ethereum were processed smoothly.
The number of games is vast, like slots and live casinos, in addition to the well-structured sports betting section, which has very competitive odds. All in all, it is a trustworthy site with great crypto gambling features, triangulated by the effortless transaction systems.
