One of the easiest way to earn free bitcoin is Coinbase Earn. You can earn $10 XLM (Stellar Lumen) and up to $75 in different cryptocurrencies: https://coinbase.com/earn/xlm/invite/x28trbhm
Just convert the coins you earn to BTC as soon as you get them!
I just started using cudo mining software. The words plug and play come to mind. Use my referral code and they give you BTC for FREEEEEEE. https://www.cudominer.com/?a=WxwpnoE7N
