While in pre-trial detention, there were two attempts to kill me: first, by poisoning, and later by deliberately delaying medical assistance for five days so that the poison wouldn’t show up in my tests. I underwent surgery twice. Now, I am in prison.
This is a sad story, but Interesting. In which country people are allowed to use smart phones or any other devices from which they can access the internet? I am sorry for your situation but people are unlikely to believe your story because there is no way to verify who you are and what is your connection with the guy who was arrested. This is a anonymous internet forum where anyone can create an account with any name and pretend to be someone.
I used to know Bitget as a good exchange and I have used their service for a while. Since you were arrested and probably the exchange were notified about it. They are centralized platforms and unfortunately, they always have to cooperate with the government.
