Before make any action you must know how much you need to have atleast a normal life,if you can get an stable income montly ,then you should consider to left or no the real work,but you must know you need to save a part of the income otherwise if bitcoin die you wil be dead as well.
i think we can use other payment for our bussines, like paypal, or other cryptocurrency as etherum, dash etc.
if bitcoin fail, the bussines still continue with paypal fund.
