Those who really have a lot of experience in trading can easily earn in the digital currency market, as they already have certain strategies, discipline and patience, and this is the most important thing in investing!
Even though if you have experience at trading crypto, you might not be able to make good money if the market is not good. I mean that in a bearish market, making high money in trading crypto is not easy at all and even those people who have some good experience need help to get things done. But yeah, there is no reason for you not to trade crypto if you know how to do it.
There are reasons behind the fact that why you would not make money in crypto if you quit job because the market never stays the same. You might be able to make money once or twice in trading but it cannot be promised that you will make money for the third time which means that you should have another source of business which would be able to fund your needs.
