I signed up for this website when some another person posted a blog about it in Steemit. This looks like an attractive platform to make money.But the truth is the only people who make money from this type of website are the one who drive people to it.
You can't withdraw your payment from it until and unless you earn 35,000 tokens.It will take a lot of time for anyone to earn that amount of tokens.Another thing about it is that if the bitcoin price goes down to a certain level then you will lose all your tokens.
So I don't think anyone should sign up for this kind of websites.The people who like to drive people to this kind of websites only do this for their personal benefit.
