TBH simple.
Just see your currency in the wallet. Do you have your local currency ? for our country we have (IDR). I'm pretty sure, each local currency are being instaled in (Stake) can support deposit from Local Transaction (BANk and other) from your country.
If you don't see your local currency, you must use crypto.
I am pretty sure my local currency is not supported, it must be because the staff of Stake does not believe my country to be such an important market to target and accept bank transactions from. Not even mention there is much corruption here and banks under the control of the government will try to take advantage of the gamblers who use their banks accounts to withdraw important amounts of winnings from the casino.
Perhaps it is the best way for gamblers in my country just to adapt and use cryptocurrencies instead of our local fiat. In nations were corruption is high and there is a literal autocrat in power decentralization and self-custody is a must.
This is a very important issue that is seen in many countries especially where the local currency is weak corruption is high and the banking system is tightly controlled by the government. Most countries may not be a significant market for international gaming platforms like Stake.com as the banking system and regulatory environment are quite complex. These concerns that banks will try to take advantage of gamblers are very real in corrupt systems banks often illegally hold money charge high fees or impose unreasonable restrictions on transactions. Cryptocurrency can mitigate such risks because it operates outside the banking system it gives users complete control over their own money.
