I have seen exchanges like this several times, offering free mining in them. It seems like it uses the same script. And I think this is a scam because we are required to submit our personal identities to get the free mining, and of course the results are very small
You were right dude, it is a scam, because their youtube video about Bityard was already removed by the up-loader.
This is just simple if the platform is legit or no bad intention to anyone for sure the video will remain active now in youtube
platform but that's not what happen anyway.
