What are some common signs of an illegal online gambling operation?

### REPLY:
One common sign of an illegal online gambling operation is the use of untraceable cryptocurrencies such as Bitcoin or Monero for transactions, which makes it difficult for authorities to trace the money flow. Another sign is the presence of high-stakes games with no limits or restrictions, attracting high rollers and potentially leading to money laundering. Additionally, illegal online gambling sites may offer exclusive access to certain countries or regions, bypassing local regulations.
