I would like to find a full time job that pays bitcoins. It would have to be something online though, and most online jobs are notorious for being scams.
If you work for Coinbase, you have the option of being paid in bitcoin.
Yeah you can use bitcoin as the main income. But you have to have a clear job. Such as being an employee or coinbase employee. Or become a moderator in this forum. Not a problem to use bitcoin as the main income
