The method to identify whether the platform is still there: whether the platform can deposit and withdraw money normally and whether the platform can operate normally is the primary method to identify whether to run.
Secondly, you should collect information and report to the place where you handle foreign exchange in time.
Collect data: keep all relevant evidence, payment records, bank flow and information including chat records.
Now that you have asked questions here, I think someone will come to you in a more direct way soon to help you defend your rights. I suggest that no matter who comes to you and says that he wants to help you recover your losses, he must be vigilant and try his best to cooperate with the information provided, because the degree of your cooperation determines whether you can recover. Don't trust anyone's lawyer's fees, commissions, relationship fees and other expenses before you transfer the principal to your bank card. Because defenders will only charge you a commission after you receive the principal.
PS: In fact, all the trading data of illegal platforms are not hedged with international foreign exchange futures, and all customers gamble in the platform, which is a black platform with extremely clever fraudulent means.
You can privately believe what I need to do to recover my loss.
