Like any business out there, online casinos have both big and ordinary customers. Big customers can be referred to as high rollers or whales - people who deposit colossal sums of money and spend big in the casino. These casino VIPs get exclusive treats that ordinary players don't enjoy. These treats are known as high roller bonuses.
An underrated Mediterranean paradise, Montenegro, is very lenient when it comes to casinos and online gambling. The popularity of online casinos has increased over the past few years, and the providers are being regulated by E-Gambling Montenegro. The licenses are obtained pretty quickly, and for a low price, so it's no wonder this is a growing industry.
