1) The most important reason in my opinion is honesty. There are plenty of crypto casinos that operate on an open blockchain and easily provide their winning probabilities, which are involved inside their games, such as roulette, slot machines and the like. Shouldn't every casino be open? Casinos on NON-blockchain do not think so.
I am not sure I fully understand your point. Could you please provide some examples of popular casinos that operate on an open blockchain? It seems like you might be confusing the provably fair concept, which has nothing to do with blockchain technology except for its use of cryptography.
He doesn't understand himself either... I am pretty sure about that. There's something about provably fair games (in-house games that can be verified by the third party), but winning probabilities for slots and some live games depend on the provider, and their RTP is usually visible, but we can't verify our bets. I guess he mixed up those two... somehow, some way.
2) A special way of entering and withdrawing money: no open movements of transactions on accounts and cards. By transferring money through cryptocurrencies, you are anonymous. Transactions go fast and without stupid confirmations, because of which you may be asked to turn your head every time or provide documents for the 100th time.
This is something most of us from here understand... but for people outside crypto all this looks like a "spaceship"! After so many years in crypto, I still make mistakes here and there, especially when I am trying out different possibilities, and in crypto, we sure have a lot of them. If we talk about crypto in general, including all coins, tokens, and chains. Wallets are a different story, but very important as well...
The headline is simple "The Rise of Crypto Gambling: What You Need to Know"! The first thing is definitely setting up a wallet, but only one wallet will not do much if you wish to experiment with "all the possibilities in the crypto gambling space". And people should really be careful with using "the right chains and addresses"! You can't believe how many people make those simple mistakes, and for newbies all that can be really confusing!
