do not underestimate this because there are many gambling sites that become scams when they are unable to fulfill the requests of users who make withdrawals, this is caused by these gambling sites having problematic liquidity (not large and stable)
every online gambling business developer must think about this because even a small mistake (failure to fulfill the request of a user making a withdrawal) can destroy the reputation of their site. coinplay developers are surely very careful with liquidity problems.
You are right. Liquidity is very important for any casino, and to maintain it, it is necessary to constantly attract new users and retain old ones. And for this, the casino must clearly fulfill all its obligations and not have a problem with withdrawing funds. Any failure can lead to a loss of liquidity.
