The right thing to say is that cryptocurrency gamblers are not interested in using CBDC because there is no difference between these digital currency and fiat. This is because many fiat gamblers in my country will be glad to use CBDC because they seems to overcome some of the problems of online banking which includes network failures and other transaction issues. Also, people will embrace CBDCs in countries where cryptocurrencies are restricted or banned because they are viable alternative. Although most casinos insist on KYC, using CBDC for gambling is another means of giving out your privacy to the casino company, banks and government. Regardless of how enticing the benefits of using CBDC might look, most gambles that are conscious of their privacy and security will always prefer to use cryptocurrencies.
