Hello everyone!

Do the casinos where we can play with cryptocurrencies are all based on blockchain, so we can control every deal, or crypto is there only as a form of payment?

Bitcoin casinos are the same as fiat casinos. They are centralized and your wagers happen off-chain. There are a few blockchain based casinos on EOS and Tron where all your wagers are verified on the blockchain.

Thank you for your answer.

So what mean that some gambling site is "provably fair", is it possible to check that somehow, if is not based on blockchain?

Bitcoin casino has not yet been developed on the blockchain technology system yet.
But just like every normal casino it is very transparent and I don't think there is a need for the blockchain technology

You can check provable fairness of a wager if you know a little bit about mathematics and cryptography. The casino will give you some part of a formula ahead of time and will even allow you to modify part of it and after your roll is completed they will show you the final part of the formula which you can use to calculate if the number you rolled matches the result of the formula.

Provably fair doesn't always have to be based on blockchain that's only one of the many ways to make it more random.

Most gambling sites have their own verifier to check each bets if you don't trust them you can also use a 3rd party verifier like this one (https://dicesites.com/provably-fair)

I know there are a lot of bitcoin gambling sites that have done it but most gambling sites have moved to off chain to reduce the spam.

I think what you are asking is if all the Crypto casinos are based on cryptography which is used to determine your roll result to prove you are not being cheated correct?

In a regular casino you go to the table and whatever result comes out of the Roulette wheel you just need to trust it wasn't manipulated. No way to check 100% you weren't cheated. Just need to rely on casino regulations.

With bitcoin online casinos, and games like dice its very easy to prove you are not being cheated because of the provably fair method.

You are given a hashed seed before you start your rolls and your rolls afterwards will all use the same unhashed seed to determine the roll result. After you are done betting, you are given the unhashed seed and can prove you weren't cheated.

Hopefully this is what you are asking for.

This is news to me. Did not know this stuff before which is why I appreciate this clear and concise explanation.

I know that a few blockchain based casinos have been developed based on my research, but off-chain seems to be the better route here.

That is why bitcoin casinos are different some would use a platform base on blockchain while the other casinos use different platform. I agree with adaseb that most casino use hash seed that is why most casino games winning percentage is base on luck and provably fair.

I think OP is doubting the fairness of casinos not using block chain platforms. Of course it can be compared. Block chain casino platforms are fair enough, you have your hash to check outcomes.

We can't blame the OP for doubting the fairness of casino, as we know there are casino games that you think it's fair but will result in exit scam where the owner can't be contact anymore. I think that's the reason why the op started this thread to ask if the op is cheated or not by the games.

The fact that there are online casinos like that is also the cost of why many in the forum are very doubtful about certain people posting their sites in here, Mostly newbie's or people with negative trust (Well not all the time) But I guess there are trustworthy one and sometimes you would never even notice that having doubt with someone sometimes is wrong, But I think cautiousness is really needed and I think it is the top priority most gamblers must have because most of us here will surely have a second thought when we are talking about risking our money, But well if you are searching for gambling site that is trustworthy and fair stakes is the one I can think off,

Well, I never have seen sites that are based on blockchain and I guess if there are one you should look for gambling site that is base on ICO and are using their own coin so you can play from it.

Does this mean the fairness of crypto casinos are of the same as the traditional ones? Where in there are doubts about it being manipulated by the house?

When we do talk about cryptocurrency then its always tied up with Blockchain technology.About controlling every deal then it would matter on servers/providers side.
If you are on doubt you can actually verified bets yet there are sites that do show up transparency about provable fair.

Some are, but as you guessed,,, most casinos that claim themselves to be Bitcoin casinos actually only use Bitcoin or crypto as a form of payment or betting currency.

Some good ones do also implement on-chain functions whereby even your bets are determined by blockchain, blocks being found and things like that. Others also use crypto inspiration with hashing to make the games provably fair.

One big clue about Bitcoin casinos worth trying is: no fiat options, no kyc,,, and dice;)

Please don't try to speculate other reasons why they are asking regarding fairness of casino's accepting crypto's . "Exit scam" is not something that he is asking and exit scam is a whole different term in comparison to unfairness of a casino (though it falls into same page if we see the outcome) but still it is not something that OP is asking.



I don't find it new. In fact it have been there for quite sometime now. In usual, casino will show you the hashed server seed ahead of the roll and you will have the control over the client seed (which you can change or randomize as you wish). Hashed server seed is so that to prove that they don't change the server seed to rig the outcome into their favour. Both client seed and server seed is then used to determine the result.

There are really only two "blockchain" based type of casinos in bitcoin, unfortunately many games can not be really provably fair or based on blockchain because the system of the game doesn't allow it. For example, a poker game can't be based on any blockchain I am aware of, hence you can play poker with bitcoin but do not expect it to be based on blockchain.

Nonetheless, games like dice can be based on blockchain in one of those ways, either it could be provably fair where you check the seed and prove that indeed the bet was correct and casino didn't screw you over with fake results or it could be based on blockchain just like eosbet for example which means it will be purely on blockchain anyway without any central controlling organization. Both are fine for gambling since both are fairly legit.

not all bitcoin online casinos are running their own blockchain. most of them are just for payment method.
and yes, if the site is running legit, you can always check their provably fair method by checking your hashed seed
so theres no need to use the blockchain tech in proving their fairness.

Pretty nice answer mate OP want to make sure the fairness of crypto casino gambling, and that's is true some site are scams so can't blame op to avoid a doubt from the crypto site, but there's a lot of fair and honest crypto casino site.

That is a good point but for me, I think Bitcoin casinos are not yet based on blockchain technology. Bitcoin casinos are there to appear as an online casino where you will be able to bet your bitcoin or other cryptocurrencies online. It's just that compared to fiat casinos, Online Casino has a fair algorithm that will determine if you will win or no. Most of the online casinos and bitcoin casinos use an algorithm where that will let them gain profits to continue operating.

As far as I know, the scaling ration of win rates in every casino is 1 win = 5 loses so they can have a profit and sustain the business. Blockchain technology is not yet applied to Bitcoin Casinos but the pros are that you can use your cryptocurrency to bet with anonymity.

That was a good question but the answer can very depending in which casino you are using.
Some use blockchain and you can even use it to verify your bets but most all of them are not, very similar to real life casinos.
For me the most important thing is to use a casino which offers you Fairness so you can verify all your bets one by one in order to make sure you are not being scammed.
When a casino has a real Provably Fair they should offer you that option

I believe this is the best explanation for op questions. There is no much different between blockchain casino and fiat casino and you can actually decided to used any and that depends on your favourite.  I prefer blockchain casino because of how transparent the whole thing are.

There are some casinos based in blockchain, those are better known as onchain casinos, they work directly on the blockchain and one example of them is Luckb.it...

The other kind of casinos (offchain) use cryptos just for deposits and withdrawals, but blockchain doesn't affect the bet result.

There are blockchain casinos ( and games ) based on Blockchain tech, fully Provably fair, high end verification process etc
Exp of which are EOSBet, TronGem and others
The rest are regular Casinos accepting Crypto from players - the list you can see on https://www.bestbitcoincasino.com/

Blockchain is not Crypto !!!

No, it's only called crypto casino or bitcoin casino because they are accepting crypto as a mode of payment.
Though there are some gambling sites that utilizes the blockchain for gambling but the non blockchain gambling games are still more popular.
For example, sports betting, they are not based on blockchain but since sports book accept crypto, we called their crypto casinos or sports book.

..as far as I know,,there are some casinos that are base on blockchain and you can check this whenever you want to ensure that it is probably fair,,but most of them uses crypto as mode of payment.
..for me,,it is better to play casino that is base on a blockchain technology because it solves the five most major problem that gamblers encountered. these are the lack of transparency and trust, the possibility of fraud, Long-awaited payments and additional fees, No rewards for customers and Anonymity.

Actually there are some sportbook as well that based on blockchain but it has been a long time ago and yet nowadays more sites are secure their own fund by themselves to store it on their cold wallet as well so if there is something happened on the blockchain, they might not lose it as well. So actually blockchain and crypto is just a same thing though, because everything is basef on the blockchain, only the support system is different

Most casinos where you can play with cryptocurrencies are not based on blockchain technology because it has yet not been adopted to casinos. If you have used bitcoin casinos before you probably noticed their slots and games are from other providers that are not even related at all with cryptocurrencies so it's impossible to be based on blockchain.
They are called bitcoin casinos because that is the main currency used on their platform and because most of them allow you to play anonymously without needing to complete a KYC.
You could try Stake, a casino that is probably fair and runs on Blockchain, meaning you will be able to verify every single bet made by everyone in their games.

How would it be different with the current set up?
You are talking about an sportbook that is based on blockchain and there's one existing in the past. please can you tell me what site was that?

Seems like you caught my interest.

That is why Eos and Tron based casinos are getting popular now and this adds to Eos popularity in the market, I have participated in one Eos campaign about gambling and I'd like how they make the betting very transparent soon we will see a lot of EOS based casinos but still people want to get paid in Bitcoin.

There's some confusion as to how a casino becomes a bitcoin casino, a fiat casino, or even a blockchain casino.

To simplify things, we can look at this matter this way:

1. Originally, the industry had fiat money-only casinos (which means only USD, EUR, etc. are accepted)

2. When Bitcoin entered the scene, the industry started to have Bitcoin-accepting casinos (which accepts BTC, ETH, etc. but still follow KYC/AML and do not run on the blockchain)

3. When Bitcoin became popular, fiat money-only casinos/betting sites started to accept cryptocurrencies as a payment method, thereby creating a new type: hybrid casinos (accept both USD, etc. and BTC, etc., still follow KYC/AML, and do not run on the blockchain)

4. Then there are online casinos that accept cryptos and offer provably fair, proprietary on-chain games (e.g. dice, table games). Many regard this type as the real Bitcoin casino or aptly called crypto casino that run on blockchain

Keep in mind also that not all online casinos that offer provably fair games accept crypto and/or run on the blockchain.
BGaming, for example, is a game developer whose games are provably fair. But you'll find BGaming titles in casinos with KYC, etc. Yet, those casinos are not on the blockchain.

To go back to OP's question: not all the casinos we call 'bitcoin casinos' are based or run on blockchain.


Hope this helps,

Majority of the casinos are not based on Blockchain. i.e every results of your bets are determined using random tools. Cryptos are used for payment. But, there are casinos which works on chain ie every rolls placed through their smart contracts on the blockchain. So, the bets are provably fair. EOS and Tron based dApps offer decentralized gambling. Recently EOSbet started Bitcoin wagering on their blockchain.

I guess that sportsbook is directbet since they're the only popular sportsbook that was constantly sending transactions in and out on every bet.

We can verify our bets on stake but they don't run on blockchain though if i'm wrong with what i've said then we should be able to check each bet through the blockchain.

A lot has been partially mentioned by other members, but I want to make a summary and add something new as well. There are different kinds of casinos. Some are just accepting payments in cryptocurrencies, so they are not based on blockchain. Other Bitcoin casinos have a provably fair algorithm which as far as I understand requires a blockchain to work, since it used cryptographic hash: https://bitcoinchaser.com/provably-fair-gambling/. There are also Ethereum-based casinos that operate on smart contracts and can also be counted as blockchain-based ones. There one can be 100% sure that the payments will be made in case of winning, because they will be performed automatically by the contract.

It is not really THAT complicated, a fiat casino is the one that takes fiat and not accept crypto, the crypto one is the one that takes crypto but not fiat, the blockchain one takes crypto but also run by blockchain itself without actually relying on a websites coding. So all in all its pretty clear distinction between all of them.

Here, if we have to talk about what "based on blockchain" means either it means something like eosbet where it is purely based on blockchain without a central organization changing whatever they want whenever they want and just let it run on blockchain technology or basically almost all decent dice websites that run on their own servers but makes sure they have provably fair which could be checked with blockchain technology to prove people casino is not scamming them.

Having a decentralized transaction is way better than fiat casino which is visible. I agree, EOS was a good platform and it can verify all of the transaction in the blockchain. It all depends on the transaction, so if I were you, I'll choose the better one.

There are not many on-chain games left, the only i know about is luckyb.it, it was and is a great gambling site just that their minimum bet raised considerably since the worth of fees nowadays.

Its great to have this plinko back again but it seems that luckyb.it is not that active anymore compare to the current time. I saw many big winners coming from that site and it is pretty good to keep that up to date. But due to the support team, I do not think they have a good management of their thread so the only player that play there are the old player. They can't gather a new one

If I get you right, I think for now you can only play casinos using crypto currency as form of payment though we have few casinos that are based on blockchain technology but most of the ones I have got myself engaged in so far only offer crypto as means of payment just like the normal traditional currencies.

Some casinos are using block's hash as references as it will not be manipulated by casino hence it will be open to check for anyone for proving fairness. Other than this I am not sure about in how other ways, a casino may make use of blockchain like storing some gambler or gambling related data which is never need to be fortified by anyone like that.

There are also ones that basically roll the dice according the last digits and all that but that is pretty old school. I remember satoshidice on its very earliest days where you have to send money to a wallet specifically for the % of odds you want to bet on and you got it back with profit depending on what the hash was for that transaction.

Literally, the hash for your sent transaction was the result of the bet as well, easiest way to check if you win or not, simpler times. Of course, that required for you to send money and receive money which was both heavy on fee and wait times each time you bet compared to less than a second it takes now when its off-chain but its was still more trustworthy that way, you didn't had to do seed checking and all that. I miss the good old days.

Most online casinos I know just use cryptocurrency as payment from e wallet.

Can't they make use of blockchain tech for the transparancy of the game?

There are very few online casinos (https://to.crwd.cr/cm) right now that uses blockchain tech though I hope more will arise. It's because blockchain casinos are a lot better than traditional casinos in terms of transparency, information security, operational costs, and accessibility. Traditional casinos have many hidden tricks that gamblers are unaware of. Also, many casinos take gamblers' personal informatioin and these include but are not limited to debit&credit card details that can leaked when not secured 100% but with blockchain, these data is secured more safely. Plus, the operational of online casinos are a lot lower than traditional casinos.

In short, blockchain casinos are therefore safer, easier and better than traditional online casinos.

Bitcoin casinos not so based on blockchain but  blockchain technology will bring a new level of transparency and fairness to the gambling sites or industries.Now many gambling sites use their own way to mdeposit and withdrawa.   

As of now there isn't much bitcoin casinos on the blockchain technology. Everything is developed on the common scripts with their own house edge preferences. Recent days there were more focus towards the development of bitcoin casinos on blockchain platform, as suggested it'll provide next level of transparency to the users.

I don't think so bitcoin casino's are not operated on the blockchain and the name is not in any way related to bitcoin other then acceptance of bitcoin as a form of payment on the platform I gues bitcoin casino is the same as the old paper faint casino.

You should understand the different between Bitcoin casinos and blockchain casinos.

Bitcoin casinos are betting sites that accept Bitcoin, simple as that. Just because a site accepts BTC doesn't mean the transactions (payments and withdrawals) are decentralized.

Blockchain casinos, on the other hand, are betting sites whose payments/withdrawals are done wallet-to-wallet. And those which we call "dApp casinos" which run based on smart contracts are those that now revolutionize online betting in a fully decentralized manner.

Provably fair was created because of some people think that they are being cheated by the gambling site. We have different verifiers in order to verify that the dice that you rolled was not cheated.

You can try and check the verifier here if you feel aggrieved https://dicesites.com/.

Bitcoin casino are simply that you are transacting with bitcoin to the casino site, account or something, it might not be decentralized because it can be monitored and its outcome can be manipulated.

That's good to know the first on-chain EOSBet casino platform with system bitcoin. Could you kindly share us your link to the game? or your game ann thread for participation?. Interesting to know that this has taken place on Blockchain.

Crypto casino and traditional currency casino are the same cause the players are all treated with the probably fair deal and run on off chain which always result in house edge base on the centralized mode of operations, cosino deposits are either done in faint and some time with cryptocurrencies that is for the cosino that have the feature to accept crypto deposits.

Bitcoin casinos are run on the blockchain because they use contract address for all transactions and that is only made possible using the blockchain. Each play is associated with a unique bitcoin address which will be used for all deposits from the player.

I think bitcoin casinos are not based on blockchain, it is simply created outside the blockchain. It works same as how real life casinos work, the only difference is that the form of payment is via cryprocurrency.

There are casinos that are blockchain based but I did not see it popular.
Most casinos that offers games like dice are based on provably fair system and it can be verified that the system is accurate.
The blockchain system is very useful for the payment system, we can play it anytime since these casinos are online 24/7 same with out payment processor.

Most casinos are only regularly based but there are also those that provide blockchain based casinos like Tron. Such casinos are rarely in demand by gamblers because all they need is a payment from the games they follow so the blockchain is only used as a payment in the form of bitcoin or altcoin. Not many people use blockchain-based casinos even though casinos like that make it easier for us to transparency the game so we won't feel cheated by the bookie because we can monitor it transparently.

Some casinos are blockchain based. And for some they're not. But, if we are talking about provably fair in here(based on OP's question and second question) provably fair is not based on blockchain. We are using verifiers for it not to be bias. Sometimes, we use 3rd party programs for us to verify our bets.

Yes bitcoin casinos are based on Blockchain. Blockchain is a technology of bitcoin, it's helps to run bitcoin smoothly not only bitcoin it's a technology of all cryptocurrency. Blockchain obviously a important part of bitcoin casinos, it's a technology which maintain cryptocurrency properly.

I think that cryptography exists only as a payment. The same thing happens on the stock exchanges. You bring your bitcoins to the stock exchange, perform dozens of trading operations, but your stock wallet remains motionless.

Most gambling sites only use bitcoin as payments like those sites that are already popular in this forum. However, there are some sites that use blockchain as the basis of their gambling system even though we don't find many sites because it is less popular with other gambling sites and can even be caused by members not understanding the workings of blockchain-based gambling sites.

Not all of them, but i think there is a crypto casino that based on blockchain, i forgot the name.

Most crypto gambling site/casino is same like the fiat one and mostly not based on blockchain. I think only the payment/currency that they use, cryptocurrency which is based on blockchain.

You can play gambling with bitcoin but i do not think that the casino are blockchain based. All the casino are centralized and they only use bitcoin as money to gamble, deposit and withdraw.
We are yet to see block chain based casinos which will be decentralize ofcourse.

I think that ordinary player gambling sites do not care if the casino works on the blockchain or not. For players, it is important that they can add bitcoins to the site and easily wisdray them. Also it is important to them that the game was fair and interesting.

There are multiple casinos based on blockchain and some of them are Stake, Edgeless or True Flip but this are just a few of them which are quite popular because a lot of new ones have appeared recently. The examples I gave are casinos completely based on blockchain and they are all provably fair, meaning you can check every single bet made on their website so there is no chance someone could cheat, not even the owners of the websites since every information is available publicly for everyone.

I think you are misunderstanding the concept of gambling at crypto casinos. They are not on the blockchain but the bets which happen on them are.
They are verified by seeds given for each bet. I learned this is how they validate each and every bet to be fair to the players.

So most people in this topic write that they don’t need blockchain to make bets. It is only needed to make payments to gambling sites and back.

There are games in which the number determines the blockchain, for example, chain-bet,com or winningbet,io it is an absolutely provable solution.

Yes, sundaylottery..org also uses only smart contract from A to Z though it is more a lottery at the moment.
 
But many casino games are difficult or impossible to implement completely on blockchain due to its limitations.

No bitcoin casinos are not based on blockchain. Bitcoin as normal as others casino it's not depends on blockchain. Blockchain is the technology of cryptocurrency, it's basically work for crypto not casino. Blockchain is a technology of cryptocurrency it's not work for casino so bitcoin casinos are not based on blockchain.

You are absolutely right. I also have not seen a single casino based on the blockchain.
However, I saw holding various raffles where various souvenirs, silver and gold coins were played.
I saw how participants make a fixed bet and choose one digit out of 16 (in hex format).
When all the numbers are occupied and the contributions are paid, the presenter calls the number of the bitcoin block that will be mined in a short time. The last digit of the hash of this block determines the winner. This method of conducting draws can be adopted by the casino.

In the platform that I follow, they have their algorithms based on blockchain, each game or each move it is possible to do their audit in the moment by the same player and see what was the option that should have chosen, we must also start using the Provably a lot Fair that is very legal, the good thing about Blockchain is that it is impossible to cheat or corrupt your code, I think that this is what gives confidence to the players.

Have you heard the idea of Decentralized Gambling ?  Currently all or most of the gambling sites are centralized but i can see we will have decentralized gambling sites in the future and then we can say that casino are based upon blockchain technology.

It seems to me that it is not advisable to do this, in gambling there is enough speed, which is developed by the processing of operations in the database. Own blockchain does not greatly change the speed of operations.

It really depends on casino sites you are talking about.  I know EOS base casino sites are completely decentralized but most of the gambling sites I have come across especially those that are been promoted here are centralized casino sites.

Some other gambling are adapting blockchain platform, but majority i know are more on using the normal features for payment gateways like credit cards and fiat currency.

You are right most gambling platforms before now use the old traditional financial method for they deposits and withdrawals, but in recent time gambling industry is now taping into the potential of the blockchain and adopting the decentralized method such as the use of bitcoin and other altcoin for they gaming operations.

Not all online casinos are based on blockchain but still theres a few of them are now adapting blockchain technology in their platform.
You can verify your dice bet in the seed that why onkine casino are providing fairness in the site to make player being aware that they not being cheated.

A player according to his statistics can look at his winnings and losses, as well as the amount that he has on his balance.
Other people do not need to see this information, although the blockchain may allow them to do so.

There are about three types that "blockchain" is used but they are all on different levels. One is the simple place that has crypto as a payment and that's all, most of the sportsbooks are like that because honestly there is not that many ways you can use blockchain on a sportsbook, it requires to be centralized to add and remove games and all that.

Second one is the dice games type which is basically all unrelated to bitcoin except the fact that you play with bitcoin and you deposit/withdraw bitcoin and they also have provably fair which means games are backed up by the blockchain technology which is great of course.

Third one is the decentralized casino which basically is just purely off anyone's hand and all based on blockchain of a coin in a dapp manner so its almost purely blockchain.

Yes, I also agree with that. The Blockchain technology in the casino is only used to launch the payment process (deposit and withdrawal) besides that the blockchain has not been used as a system to run casinos.

During my practice, I have not yet met a decentralized casino. Could you give me a link to such a casino.
Is this something like decentralized exchanges, only there is not trading, but gambling?

Decentralized casinos do exists, they are the dapp versions rooted from certain coins, right now the most known one is eosbet which is a decentralized casino and right now they basically have dice only (they have crash and baccarat too but I really think dice is what draws people to their website). It is not a "casino" perse but they are really getting there.

There are other examples too if you check the dapp world and see but they are basically the same except couple of trust issues removed, after all if you trust your dice website than decentralized is not really important, for example I trust primedice enough that its basically as trustworthy as decentralized for me, same with stake too. So all in all it all depends on what you are looking for but they do exist out there if you look for it or at least google it.

Recent days in the gambling network we haven't got much of dApps. Eosbet is the one that function on the blockchain platform while most of the gambling websites we use now were much into the centralized service with cryptocurrency acceptance. Blockchain into gambling is a complicated process which is quite hard to develop without flaws.

Most lottery with cryptocurrency acceptance marked its entry and those were promoted with the smart contracts network as the lottery service render itself had their own ERC-20 token. As gambling doesn't require more of regulation same as that of the exchange services we can expect the future of casinos to be fully on blockchain to enrich effective functioning.

I guess not some are based on blockchain but not most of them. all these casino's who accept crypto payments or deal with cryptocurrencies are just some numbers there they are not actually betting with bitcoin but when you withdraw they give you btc according to the number you achieved just like how banks do it. Casino's can not control the bet amounts as they are fixed even before you want to play so that's how you can verify if they are cheating or not. and no they do not cheat because they don't need to. you are playing with them and they have the much higher bankroll to handle big losses which you can not.

I think that is the explanation of what centralized crypto gambling is. I mean if you just deposit your money into a casino and then you just play there the way you want it doesn't have to be bitcoin that you are playing with, it could be basically a number that represents how much bitcoin you have and win/lose that is it.

It doesn't really change much in the gamblers hand because you end up with more or less bitcoin according to what you win or lose but in the end there are no transactions going around in the background involving your money. Its not like early satoshidice days where you literally have to send money and if you win they sent you back and so forth. That is what decentralized casinos are trying to bring back to remove the central ownership of the casinos.

Haven't you met a casino that requires you to verify the KYC process? For me, if there is a KYC in a casino i already think that it is a centralized casino which is someone is controlling the casino. Although the KYC process to some casino requires only if you met a certain level of verification like depositing/withdrawing a large amount of crypto/fiat.

People are interested in whether there are gambling sites where the game is not based on databases and numbers, but on the basis of the Bitcoin blockchain. However, I do not see the point. If you play games on the blockchain itself, you will need to pay transaction costs, and this is expensive.

i think not all crypto related gambling sites are blockchain based  . some gambling sites accept cryptocurrency as payment and you will still need to pay for the transaction fees before you send your funds into your gambling account  and the fees will not always be expensive but it also depend on the price of cryptocurrencies  . i think blockchain based casinos are more fair   .

Well for today i don't play gambling games of casino based on the blockchain technology in cryptocurrencies because my service of gambling games based on the blockchain they still don't give games casino gambling based on the blockchain technology (casino dapps) for today i just played gambling dice game based on the blockchain technology and i used Tron coins as payment method and wagered because it is decentralize application dapps gambling games which was built on Tron blockchain technology.

I see no reason to create a casino based on the blockchain for betting.
Using cryptocurrencies to make payments is an excellent solution, but for direct betting, this is an excessive waste of commission fees. Much better to organize everything based on the database.
