Leaving the job in the entry level of crypto currencies is not advisable.This market could not be expected to remain forever.Instead,we should do a job and work side by side in bitcoins to earn more profits.Here risk bearing attitude is more needed.
Quitting your stable job for crypto needs a thorough thinking. The decision would come to you and your wife and for the sake of the children. What if you fail in crypto? What is the plan b?. So for me we can do both crypto and work then if you are making it big. Then you can decide which is to retain.
