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 Out of these three I am using the second one only, as I knew about this forum only a few weeks ago so I am totally new to signature campaign.
I am earning a better amount from Faucets, especially from the list of faucetbox.com , but still I am searching for more ways to earn as I can give more time also to earn online. I have heard that from signature campaign we can earn some better amount.
