I remember when Atlantic City was clean casinos and James Bond movies. I was there for 40 years. Watched it decline. Watched online casinos start taking the business.
When I played roulette online, I learned something the old casinos never bothered with: currency conversion is its own house edge.
The Invisible Fee
A player from Canada deposits $1,000 CAD at DraftKings (USD-based). The exchange rate is 1 CAD equals 0.75 USD. So $1,000 CAD should equal $750 USD.
But DraftKings charges a currency conversion fee of 2-3 percent. Instead of receiving $750, the player receives $727.50.
The player thinks they deposited $1,000. They deposited $727.50 in actual playing money. $272.50 vanished in fees and exchange rate markup.
This is 27 percent of the bankroll gone before a single roulette spin.
How It Works
When you deposit, the casino converts your currency at a midpoint rate plus a markup. The markup is the fee.
The "midpoint rate" is what you see on Google: 1 CAD = 0.7499 USD.
The casino's rate: 1 CAD = 0.7299 USD (worse for you).
The difference is the fee.
Which Casinos Do This
DraftKings explicitly charges 2 percent for currency conversion. Bet365 charges 1-2 percent. FanDuel charges 2 percent.
Stake (which operates in crypto) avoids this by denominating everything in USD or crypto. If you deposit Bitcoin, no currency conversion.
The Player's Non-Choice
If you are in Canada and want to play at a USD-based casino, you have no choice but to convert currency. The casino will not accept CAD.
So you either: pay the fee, or don't play.
This is a cost of doing business, not a fair market exchange.
The Comparison to Physical Casinos
Physical Atlantic City casinos do not charge currency conversion fees. A Canadian player can exchange cash at the casino's desk at a fair rate.
Online casinos extract this as a hidden fee because the player cannot comparison shop easily.
Withdrawal Conversion
When you withdraw, the same fee applies in reverse. If you withdraw $750 USD to your CAD bank account, you receive approximately $1,020 CAD instead of $1,030 CAD.
You lose another 2-3 percent on exit.
For a player who deposits $1,000 and withdraws $800, the currency conversion costs approximately $30-$50 total (2-3 percent on both sides).
The Crypto Advantage
Players who use Bitcoin avoid this problem entirely. Bitcoin is borderless. 1 BTC is 1 BTC regardless of home country.
Stake explicitly markets this as an advantage. No currency conversion. No fees.
This is one reason crypto casinos appeal to international players.
The Math
Over a year, a player who makes ten $1,000 deposits and withdrawals loses approximately $300-$500 to currency conversion alone.
For a casual player, this might be negligible. For a serious player, it is a 3-5 percent drag on every deposit and withdrawal.
The Hidden in Plain Sight
Casinos do not hide currency conversion fees. They are disclosed in the terms of service, buried in the payment section.
But most players deposit without reading the terms. They are surprised to see their $1,000 become $970.
The Recovery Path
If you play internationally and avoid currency conversion fees, you gain a structural advantage. Use casinos that operate in your home currency, or use crypto-based casinos.
DraftKings' 2 percent fee is not unreasonable for converting currency. But it is worth understanding before depositing.
I wish the Atlantic City casinos had found a way to charge this. It would have extended the business another decade.
Instead, they stayed old while online casinos figured out how to extract margins we never imagined.
