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 a list that you create is very precise, only now it can be relied upon to find or produce bitcoin, and the largest sequence is still the signature campaign, sometimes there is also the added gambling at the top, because it can earn large amounts of bitcoin

yeah signature campaign are the safest way to earn bitcoin along with service offering gambling could be also a way to earn if you are lucky enough
