If you rank is legendary you cannot earn 0.1 btc a week because I think the payout of legendary is 0.03 to 0.06 only . Unless you have two legendary rank you can earn 0.1 btc a week for sure. Many people here for sure earn 0.1 bitcoin because of their alt account. But I dont recommend in alt account must better if you have only 1 account because you are focus of what you doing here.
