How exactly were you scammed? What say the terms & conditions when you invest in their cloud hashing?
If you have proof of your claim, you can directly start a court case in London.
The problem with that, is that is too costly for what they stole and they know it. They took from me a little bit than 1 BTC. Currently it runs at current price for 24K and just expenses in lawyers probably will take it if I win the case. The best thing is to use that money to compete against them and take away their market share. Exfiltrate money from their pocket to our pocket. Effective. But yes eventually I will be pursuing the legal route even if that means losing some money. Is not the right time. It will come.
