Let us tell you about your situation and give you an idea for those who have already started investing. If Bitcoin will down 50% tomorrow and at the same time your income stopped for a few months, do you have enough cash to run a basic life without selling Bitcoin?
Your investment is not supposed to be something you start selling just because you're facing financial deficulty that you're battling for months or a year. If at the slightest financial setback you activate a sell option, what that means is that you're not a serious investor that wants to get anything tangeable from his investment.
Because bitcoin is relatively volatile, along the time when you're still invested, there will come times of DIP and bull and that's not suppose to influence your buy/sell decision. It's always going to be better that you set up structures like an emergency fund and focus on creating better cash flow or possibly having an alternative stream of income such that if an income stream shuts down, You can easily open another income stream without neccesarily selling your bitcoin as a means of surviving on a temporary bases.
