It's very good that you want to quit your job for crypto. But to get a stable income here, it will not be enough just to buy a coin and wait for its growth. Here too it is necessary to work. But I wish you good luck. Many have been able to throw off their duties to someone and now enjoy life and I wish you the same.
but if you have experience in short-term trading, I think quitting your real job is a good choice, so you can focus on monitoring the chart at any time. do not be afraid because it does not have a steady income as long as we have expertise in trading, even the income you receive will be greater than your salary every month. but if we quit the job, without the skills, of course it becomes a hard struggle to survive
