Almost 0.2 BTC from websites that let you earn, like Bitcoinget and Bitvisitor. Most of it was from doing the tasks on Bitcoinget.
I tried once but the payout is too little. 0.2 BTC ganna take some time..
Very long time. I gave up when I accumulated about 0.015 in almost one month, hitting free faucets from time to time. 1 BTC would take forever and I doubt anyone have the patience today
