It is more advisable to have a permanent work and a basic salary monthly than to rely only in earning bitcoins. To make your time more productive you must look for permanent work that can shoulder your monthly bills and basic needs. And can do earning bitcoin in your extra time or as part time activity. Earning bitcoin is another opportunity to earn higher in addition to your basic monthly income you earn by working in a company or any institutions.
It depends. If you can earn your bitcoin in a way that allows you to develop personally it is certainly preferable over a large number of jobs in the regular economy. If you want to make your money by affiliate or marketing I feel you have to remember that while it can be a relatively easy way to gain money，it is almost certain that the good times (like now) are finite and that it may not be trivial to use this skills to translate back into the old-fashioned economy.
Now, it is obvious that necessity trumps other considerations, so while I agree that this is not necessarily bad: Being Unemployed Drives People to go to Bitcoin, I would not encourage the converse.
