I have already visited their youtube channel and they published their last video on 16 May 2020. Yeah you are right their domain is powerful enough but their youtube or social media activities are too weak. Even someone have commented on all their youtube videos that he got scammed but they are not interested to reply there which is obviously unprofessional.

When there is trusted and professional mixing service provider like chipmixer then running after this type of mixing platform is nothing but taking risks.
