All the key advantages mentioned for gambling with cryptocurrencies were also available with the fiat based gambling platforms. In my personal view I find the cryptocurrency acceptance/usage into gambling as the key advantage. If an user tries to use cryptocurrencies into gambling, he/she will never go for fiat based gambling anymore.
Other than this, the games being developed over different blockchain based platforms make the game provably fair and easily checked.
Exactly these two points are more important than all others!
1. Acceptance/usage - We can gamble from any place! Before for online gambling I needed bank account, and they were checking all my transactions! PayPal, banks, extremely high fees for withdrawing in my currency. On all that many sites don't accept gamblers from my country. Crypto gambling solved all that! Only with crypto I started my online gambling experience, and I don't plan to quit and go back to land based casinos, or fiat online casinos.
2. On blockchain, you can check is it provably fair! Anyone can do it easily! It's what makes it more fair and transparent!
I am here for years, trying out different blockchain casinos, and trying out new things, new possibilities is what makes crypto gambling experience amazing! I didn't hear for fiat casino where you gamble and you get tokens for your money spent, tokens that you can stake and get dividends from that on daily basis! It's possible only in crypto gambling industry!
