In trying to address this, I will try to be as explicit as possible. May i say that there is no best way to this. Your DUE DILIGENCE is key. One at this juncture has to be very strategic. Below are some workable means to an end:
1. One of the best practices is to search if your broker is regulated by any agency. If this is in the positive, then your chances of getting your money back via this channel becomes an access gate. Upon verifying this, get all your proof and send a complaint mail to either SEC or CFTC for investigation. If it turns out to be that your broker was either negligent or manipulative which is against trading ethics, the Regulatory body would order them to recompense you. Upon their failure to follow SEC's order, their operation license would be revoked and SEC would bring action against them. However, if your regulator is unregulated, it follows to say that you have gambled with your hard earned money and beware that this kind of risk is captured under the slogan, BUYERS BEWARE'. No legal protection. If the later is the case, you have no business with SEC since the total assumption is that you have been scammed by some scam artistes who pose as brokers but who are not in real sense.
2. Some will advise for a charge back which may be plausible with like 10% success rate. Remember that you never consulted your financial institution before making this financial decision. Also, your means of payment could be cryptocurrency which is untraceable. Let me ask; " HOW DO YOU WANT YOUR FINANCIAL INSTITUTION TO GET THE MONEY FROM'? Just note that if this is the case, anyone offering you chargeback service merely wants to make away with your money. You can only consider this is it is real inter-bank transaction. In that case your chargeback claim would hold water.
3. Needles to say that you must as a duty report to any law enforcement agency where you are resident for prompt action. This could be any authority saddled with discreet investigation. The FBI is a good go option for you. Ensure that you file with proof. Your chances of getting your money may be slim since these companies are registered with fake identities. With the use of data track network, tracking them down is not hard. But the FBI is over burdened with too many complaints which might it take longer than necessary to get to your turn. File with them but still look for a way. In the recent time, their ability to retrieve such funds has not really been easy since their are more state related issues to attend to. Also, their is outright of cryptocurrency in some jurisdictions. If you fall into the category of these countries, kindly look for alternative.
4. Do not go through litigation if the company is not regulated. Let it sink into your head that it is not one of the roads that would lead you home. Who do you want to maintain the action against? A ghost? You can only maintain action against a real person because of the fundamental principle of fair hearing.
5. This last option may be the most plausible if you can get a trusted company. There are some asset recovery companies but 80% of them are operated by scam artist. That is where the work is. Knowing where, when and how to your problem. Desperation should not even be on your heart at this point. Take a deep breath! Pray; if you are the religious type. Do your due diligence. There are a good ones that you could reach out to. PLEASE; ensure that you do not make upfront payment. That would be another scam line. There are some like TIBEX INC, AXA RADAR. Also, there is HORIZON SECURITY. None of these companies would accept your case without proof since they must obtain an authorisation from the requisite body before acting. When you go to the latter by filing through admin (at)HORIZON-SECURITY ORG, it may take some days for them to reply but you may choose to be patient. Some of their personal or tech staff left some big tech giants before joining the company and have good knowledge of operational tech models. If you have all the documents relating to your transaction, getting remedy from them could be an easy ride. Peradventure they drop your case because you do not have the requisite documents, you may contact the other two. While doing this, still maintain your action with the law enforcement agency.
Finally, may i advise you never to invest anymore. Learn trading if you desire money from the futures and options market. It is a very complex transaction which requires patience. In the interim, leave your money in your bank account.
I hope you find this helpful!
