still do both of them is good option, for me with bitcoin i can save more money than focus only at real job, i can get double salary some from real job and some from bitcoin. so i think if we can manage our time , do both of them is best option.
You hit the point, we will need to manage our time not to focus on 1 source of income because multiple source of income is great for us who are looking for big income every month to compensate our needs.
my friend using all of his earning in bitcoin as investment for retirement day, and use salary from real job for daily cost, i will use his management too.
my plan reach 100btc for retirement day.
That is a good plan, 100 BTC would be a great amount by the day of your retirement, you should consider yourself lucky if you can generate that amount from your savings and you should be discipline enough in order for you to save that amount of bitcoin. If in your retirement day, the amount of 1 bitcoin is $10,000 then that is a lot of money already to enjoy life.
with current method, trading, mining, giveaway, campaign etc. i can earn arround 1btc each month, my plan to have 100 vga to mining ethereum, then start saving btc for retirement day, im sure in 5years i can reach 100bitcoin.
