This is my method in earning bitcoin. I go for forum site and faucet site for earning capital funds. Then invest my bitcoin to online investment site. Other option is trade my bitcoin in trading site. Buy for stacks and sell it as price is up. And last option is gambling I try my luck to bet to grow my bitcoins.
I think personally !
All ways mentioned are common ways. Which can take time and as you mention that you first do fauceting for capital, it seems time taking.
Second thing online investment site are mostly scam I think you might have experienced. Trading is one the good way of getting good ROI but still it need big capital.
ICO or Stacking are also non predictable.
Better way invest time to understand blockchain technology and try to apply it to build some thing sustainable which can give residual earning.
