buy and hold it.
What I have no extra fiat? I have learned about Bitcoin, is amazing and all, but I don't have any fiat neither any of my friends have any fiat to risk on Bitcoin so they stopped caring
If you have no fiat to invest in Bitcoin, then you have 3 options:
1)Find jobs that offer to pay in Bitcoin.
2)Offer to sell or provide goods and services for Bitcoin in return
3)Join a signature campaign here in the Services sub forum of Bitcointalk
Good luck!
