Totally agree with previous comments here. It's possible to earn a lot of many in crypto (at least it was possible some time ago), but the earnings were and are unstable. Also there is always a risk of losing part of invested funds or even all. And this is a risk which we must take or leave the crypto-market.
So, if you have not earned enough to survive a long downtrend and don't have other source of income, it is very bad idea to quit our main job.
