1. Dont click and browse non recognized site to avoid phishing.
2.. Always ask first the people on this forum whether the site is legit or not.
3. Dont put too much money on that site so if ever its really a scam, the amount it can get is minimal.
4. If it looks really legit, try some few games with few bets at first.
Being cautious costs less than not being aware at all. Dont let our greediness and dumbness takes over our financial life. Be safe people.
I'm surprised that he did not even remember the name, you always remember people who scam or do you harm, I guess he is not active in this forum or any forum about gambling and cryptocurrency, because he is not aware of this kind of scam, it's a lesson learned, tell your friend to browse here from time to time.
