Not really. Online crypto casinos are digital gambling platforms that accept crypto as a payment method. They can also accept fiat currency. This is a lot like a traditional online casino but with the added convenience of having more banking methods.
Blockchain casinos run on blockchain entirely and rely on blockchain technology. These platforms are as secure as possible, so hacking these casinos or cheating is impossible. This is like a casino with digital ledgers where information about all transactions is recorded.
