DailyCoinMine.com Review

I joined this site dailycoin-mine.com through a referral link on 2nd of July and got a $400 bonus amount in my balance. When I tried to withdraw, they told me to wait for 4 weeks. The balance continued to grow on daily basis. They told me that on 31st of July, 2018, I can withdraw. Today, when I tied to withdraw the $4200 balance in my account, I was told to pay first an amount of $99 as tax to a 'so called' wallet address of IRS (Internal Revenue Service) of US Government to approve the earnings withdrawal. I asked to deduct the same from my account balance, bt they denied and when I asked 'What if you deny the withdrawal after I pay this 'so called tax' to IRS ? Is there any guarantee of withdrawal ?', they ended the chat and since then, no response. They're PURE SCAM & FRAUD. Jst BEWARE of them, guys.
