On-chain transaction fees are always one of painful experience for blockchain users including gamblers. It is similar to Play-to-Earn games on expensive chains like Etheruem ERC-20 chain and maybe Binance Smart Chain some weeks when BNB hit $500 to $550.
When there are lot of transactions then the fees goes up really high and players find it hard to afford specially at the ETH network because for a small transfer also you have to pay huge gas and big whales in order to confirm their tx pay double or more then average which boost the fees even more.But yes you can surely try it on weekends when there is less volume but it's open 24*7 so can't say it will stand true.
It’s nonsense to use ERC20 tokens to play on Duelbits because it automatically converts all deposits to fiat. User will just waste expensive gas fee if they will use ERC20 which is known for high transaction for gambling purposes while they can use other small fee tokens to deposit and withdraw.
Isn't ERC20 token gas fee already trimmed down? As far as I know they are not that expensive anymore. The last time I transact ERC20 token, the gas fee is less than $2. Even on the tracker the gas fee isnt that much as it was before.

Besides the difference in fees during weekends or peek hours is not that huge unless you are playing with a balance that is just the minimum amount to withdraw. Nevertheless user should not use ERC20 in general if their balance is so small. ERC20 nowadays are for whales user only since most of the tokens is available on different blockchain due to the existence of bridge.
Not really, they are cheaper than before and even minnows can afford the gas fee now. But of course, if there is an option to transact in much cheaper fee, that should be the choice.
That’s a massive win indeed but this guy must be a highroller as his stake was 10,000$ on 7 fold multibet. Chances you would win this are very low and I wonder what his ROI will be on the long term if he mainly places bets like this.
Nobody knows how he ends maybe only the casino knows his statistics, for us this is an impressive win but for him this is a normal win
I assume that in one bet he spends $10K then the bankroll should be at least 10x of this bet that's the most reasonable reason
It's not easy to win with parlay bets even with 3 teams still difficult while he added 7 teams to the bet slip LOL very impressive
It was indeed a huge win but comparing the input and output ratio, the multiplier isn't that huge. It is only 50x+ since the stake is $10k and the winnings is $500k+.
What I am curious is whether he is professional or just relying on luck
I can guess the guy is a veteran. He has the courage of putting $10k at stake and won the parlay. I don't think it is only a lucky streak.
