I think the best solution is do both jobs, focus on your day job and do on bitcoin too if you have free time. Is it good ? I think it's good, so we can maximum our income with bitcoin too.
This is the best that you can do so that you cant spend your bitcoin instead you just saving it for a long time or when the price is high sell it after that wait again for drop price even a little bit and buy bitcoins again and wait for long term..
