we have to play only on well-known old sites that have many positive evaluations and leave new sites even if they offer better odds they are always at scam risk...
Not all the new sites will scam you,and also you may have bonus on new sites but understand between realistic and scam attempt if we use our common sense little bit while searching for a new gambling sites.Scam site will try to give lot of bonus and ask you to pay little to get those rewards which is a big hint for finding the scam sites.
Yes, that is true. But we don't have to trust the new site before we get the proof that the new website is legit and could be the other recommendation for other people to try. To test that site is legit or not, we could try to send some little amount of bitcoin, and play for some time, and if we win, we can try to withdraw the money. If we can repeat the process without any problem, then we can give the site to other people so they can test too. And if somehow, the other people are getting a problem from the site, then we need to suspicious.
But if the new site has a delay on the withdrawal process, then we can be suspicious, and we need to be careful, and the best is we can leave them without coming back in the future.
