You do have a lot of advantages, but not those that are on your list.
1. Most of the crypto casino will require you to go through some sort of KYC. So you no longer remain "private".
Which fiat casino lets you take out your money without kyc?
And for crypto casinos, they will let you play and take your money without kyc till some extent. Nobody can remain private on 'centralized exchanges' also if they want to sell their coins on that platform. Where goes the privacy then?
Fiat casinos have better gambling options in my opinion. But Crypto casinos are catching up.
If fiat casinos have better gambling options, I also know about some fiat casinos which started taking crypto as a form of deposit and withdrawal to allow more convenience to their customers.
3. More varied but most of them are almost identical.
I hope you are not referring to slots as they are all the same to me. Besides that, live betting also have look-alikes but we see fresh faces after visiting them though the game remains same everywhere.
4. How is crypto better any different than fiat betting? It's all the same. Just different mode of payment.
Almost no difference, except the speed. If you do a wire transfer vs if you do a crypto deposit.
5. Makes no sense.
Why doesn't it make any sense? Crypto gives you the freedom to bet from anywhere while some fiat betting sites stop you from using them due to your country's regulations or your country being in their restricted list.
