Thats really personal question and depends on the various factors in your life. Whether you are stable with or without you job, whether you can survive easily for a year or so and what is your exact plan when you will get into crypto. Does your plans gonna give you at most stability to you once you leave the real job? If yes then how and if no then what is your back up plan. Without any back up or savings (huge) do not even try to get into crypto because it is really uncertain thing to follow and we may not see the same thing in reality which you are dreaming right now. It would be better you checksum all the differentiating factors and then jump in.
