Actually there are lots of youtubers called Cryptogirl, and the one I am talking about was american or canadian. She did videos on shit-con-nect and loads of similar, and had countless followers from her affiliate links. Seemed she had invested large amounts with them, so she was always promoting them - several videos a day. Then suddenly almost all her videos vanished, and she has not been seen since. One post said her account had been hacked, but that’s not verified.
