Online casinos are proved to be safer than land based casinos as there are more safeguards against compulsive gamblers. They say that in the nearest future safeguards may be implemented in a regulated environment in the USA.
Nobody will deny the fact that it is really hard to implement a gambler playing in a land based casino. Playing online, deposits are made through accounts what makes it much easier to track players who deposit irregular amounts of money.
At the moment such safeguards at to the discretion of the online casinos only, but introduced by Democrat Congressman Barney Frank Internet Gambling Regulation and Enforcement Act (IGREA) enforces checks like these.
In case the Act is approved, consumers will get a chance to be protected, and compulsive gambling will get rebuff.
