Hi! 
I recently created a thread asking for the best methods of gaining free Bitcoin.
Most popular results:- Signature Campaign (High Paying)
- Faucets (Low Paying)
- Trading (Variable)
Now, I'm asking a different question.
What are your best methods of growing Bitcoin.
Only refer to safe investments!Thanks P2P lending and cloud mining are the first things that come to my mind. Lending can be risky, so you need to be sure of who you're lending to. It's definitely safer than gambling though..
