Players from the US…
… have been known to have the most trouble keeping up with the latest innovations in the industry, mostly due to regulatory matters. Since online gambling came to the fore, what was known as the homeland of the neon-splattered gambling Mecca, Las Vegas, quickly turned into a stern and gambling entertainment-ridden territory. US players were practically forced out of the international player pools, either by operators pulling out of the market for security reasons, or those preventing any relation to it in the first place.
With all parties looking to get off as unscathed as possible, the online gambling industry in US practically stagnated for a long time. While a few brave operators remained firm in the market, players were mostly left to wait for over a decade before the first legalization movements came about.
