I recently quit my job. I have enough to make it a few years without working if everything hit the fan but not nearly enough to retire. Make a couple of wise trades per month and I'm easily supplementing what I used to earn. It's easy work but takes a lot of patience, not for everyone!

I do not risk completely refusing official work. Sooner or later the bitcoin rate will stabilize and it will not be possible to earn as before, it is better to use it as an additional income.

I think you can only cover your own life when you are constantly investing and doing business. Because only that can make a profit. If you own btc or altcoins, you want to separate your life out of the office work then you have to see btc as a career and always have to try for what you want to achieve or simply live on your own. But that maybe too difficult.

Is a person but this is also what i am looking for. I would like to one day be able to earn a stable income from btc without having to depend on anything, anyone. But maybe I need more time and practice my skills.

Financial independence:

year 1
You have 100 bitcoin. That means you have $450,000.
You need $45,000 to pay the bills for a year. You sell 10% (10 bitcoin).

year 2
You have 90 bitcoin.
To keep this up for the rest of your life, you need to sell no more than 10% (9 bitcoin). You need $45,000 to pay the bills this year. Bitcoin needs to be $5,000 in year 2.

year 3
You have 81 bitcoin.
Repeat again, bitcoin needs to be up again.

This is called financial independence. If you rely on bitcoin holdings that is very risky. If bitcoin loses 90% of its value in a year you have nothing left.

If you're not good enough in earning bitcoins, I suggest to those people that do not let go of their traditional jobs. If you have a decent and stable job it is good while earning bitcoins for additional income. Giving up your physical job is truly a risky thing especially if you don't know clearly how bitcoin runs. I strongly advise not to let go of it. You're risking your daily needs if you remain in bitcoin only. There's no problem if you have a regular income in bitcoin; then if you wish to stop your physical job, stop it. If and only if you are having bitcoins regularly, you can let go of the job. It's your choice.

I think you underestimate people who focus on bitcoin.

for me bitcoin is a land for a living. regardless of real-world work.

not just from trading or investment alone gain profit. and we speak calmly the standard of living, of course everyone will do their best to get to the profits regardless of the loss.
for people who have extensive knowledge, always have a plan and strategy in investing or trading.

I knew some people who live only from what they earn with mining and holding Bitcoin, but it sucks if you ask me.You should have a minimum  job just to be able to justify the taxes.

Its really possible to earn with bitcoin.What should be done is that you should develop your skills side by side when you are working in a job.Then you should start to work in bitcoin related sectors in your leisure time.When you start to get enough money in bitcoins and you get enough confidence that you could lead your life with bitcoin earnings,then you could do a bold move about quitting your job and indulging full time in bitcoins.I too had previously taken this bold move and now i live a financially free life not depending on any one and earning ten times that of my previous salary in job.

Depends though when you bought your bitcoins. If you bought it way back in 2009 then for sure you will not even need to work a day in your life. If you bought like $27 worth back then then that would be worth $23,000,000 now. Talk about luck if you did do so back then. However, we all do not have that luck, we didn't even heard of bitcoins back in 2009 for sure.
