As far as I remember, Forex in the CIS is a synonym for the word Fraud. These are small firms that did not release their users' transactions to the market and could change quotes at any time. They did not withdraw money to those who won a lot, but immediately closed the account. I myself was registered in this, and saw this fraud. Nevertheless, if Forex is understood as an honest company, then it is the same money intermediary as a casino. I believe that there is not much difference between them, except that in a physical casino the payment of winnings is guaranteed.
Haha, you are right. The Forex market does exist, but these garbage companies that supposedly allow gamblers to trade on it (in reality, never making any transactions with real currency) are just casinos (of varying degrees of legality and honesty). By the way, the easiest way to understand that you are looking at a garbage is the free leverage of 10x 50x and 100x etc. - in the real market, in order to use someone else's money, you have to pay. And garbage companies give you this leverage for free because the funds are completely virtual.
