So far, I have found it to supplement what I get. It is not big by any means, but the speculation and holding can be exciting. Waiting for the fork and the later or sooner
halvening will be another thing.
Yeah it is possible to earn a living with Bitcoin but for that to happen you will have to earn allot of Bitcoin.
So I do not think that it is possible for everyone at the moment.
i hope that it will be possible for me either because i am holding some bitcoin right now
