For ordinary players I think they gamble because they got bored playing on the casino that they used to play. They want something new to try but of course they do also understand the risk of playing in a new casino because they already have an experience but for some that are completely new in crypto gambling, they don't know if what are the old and new casinos but they will just pick based on what they first see or based on what attracts them.
Not all new casinos are scams so don't worry about the newbie gamblers and in case they got scammed, they will always learn their lesson and will take caution playing on newer casinos next time.
This is very common, gamblers no matter how much they may like a game like to try new things as well, so from time to time they may try new casinos as they may find a game they like more than what they are currently playing, however even when the casino is new and there is no much information about it in the form of reviews it is still important to take our time and try to find out what we can about it and try to determine if it is a scam or not before playing there.
You'll never know till you try it by yourself as how they quote things out, but in this kind of situation where money is involved, if you are one of those who loves to explore and try new platforms for your gambling needs, make sure to use a small amount of funds to deposit, just allow yourself to know the service and all the possible benefits to attract new players.
Don't rush your feet to play and deposit huge amount, if the site scam you with small amount you can treat that as you lose from your actual bet and move forward, while if you use huge amount it's tough to forget and you will always dwell with that mistake.
BE responsible and always do your own research before moving forward to use new gambling site.
