Roulette on roulcoin.com is entertainment with a built-in house edge, not a way to earn money. This page says how the game is priced and how to stop.
1. The price of a session
American roulette pays less than the true odds. On a standard bet the house edge is 5.26%. On the five-number bet it is 7.89%. Over a long session the expected result is a loss of about that share of everything you stake.
A short session can win. That does not cancel the edge. Treat the amount you deposit as the cost of the session, the way you would treat a ticket, and not as an investment.
2. Virtual play
The virtual balance is for practice. Those funds have no cash value and cannot be withdrawn. Use them to learn the table. They are not a promise of the same result with real money, because each round is independent.
3. Before real-money play
Do not play if you are under 18. Do not deposit money that is needed for rent, food, debts or someone else's bills.
Decide the loss limit and the time limit before the first bet of the session. A decision made after a losing streak is the one people do not keep. Do not deposit again to win back the last round.
4. Limits already on the account
Your player status on roulcoin.com sets the minimum and maximum bet, the most you may stake in one round, and how often a withdrawal can be requested. Those limits are part of the account, not a suggestion.
You may also ask Support to block the account for a period you name, or to close it. Say the login and the period in the ticket. A block stops new real-money play. Virtual play can be switched off for the whole site by Roulcoin and is not a substitute for a block you asked for.
5. When to stop and where to ask for help
Stop if you hide play from people you live with, if you borrow in order to deposit, if you chase losses, or if you feel you cannot leave the table. Another deposit is the wrong next step.
