I dont think leaving your job is the answer for all of it. You can still do your work,make bitcoin as a part time job dont make it a full time job. Because we cannot say that bitcoin will be our source of income and bitcoin is unpredictable maybe tomorrow price is decrease and increase so think first before leaving your work
Personally, I treat bitcoin as a long term retirement plan, I have my retirement plan given to me by the place where I work, but if bitcoin really becomes successful then my retirement it is going to be a lot more pleasant and easy than the retirements of many persons that I know, in fact that is one of the main reasons I entered the bitcoin world, to avoid a bad retirement.
