Sarao behaved really stupidly when he was first confronted to regulators and his gains are certainly a bit "ill gotten", but it is still sad to see how the government can come and erase everything you have accomplished in your life. They will just take his money as if he had simply stole it to a grandmother whereas what he did was incredibly hard.
Dude, this post is an Award winner in Stupidity. First, you acknowledge that his gains were ill gotten, then you are crying that the government took it away, specially because it was hard work to get it. So had it been easy, no problem?
Replace Sarao's name with Tony Soprano/any villain in your post and read it again, to see the incredible dumbness of it...
