I would be cautious sending money towards Wikileaks and their "cause" of freeing Assange. Check out this thread of a guy who donated $5.000 instead of $50. He was trying to get hold of someone to tell them about his mistake. He has been unsuccessful so far. Besides that, someone who is in some way connected to one of the Telegram groups accepting donations advised him that he can create his own campaign and accept donations! Who knows which of those activities are genuine and which ones are for filling some scammer pockets.
