The slogan of btc flow say crearly "Business Ponzi Game" Ponzi is a word with a very good know significate. Ponzi= SCAM. I use the page as free user on level one. Get 130 refers and withdraw a little portion of BTC. A lot of users laugh about free users because they invest and call us "poor faucet lickers". Who is laughing now? We laugh at the end of this SCAM.
