It's important to have some money in fiat money on stand by so you can buy the dip when the prices fall down.
This is why I always encourage investors not to quit their job because they made a little money from bitcoin trading/investment. You need the income for times like this when the market is in a bearish state so you can afford to buy at good positions. And still be able to take care of your bills without having to sell your bitcoins at a loss.
A good bitcoin investor will always consider a plan B during the course of investment no matter the amount on has gained from bitcoin investment, having a job that brings in a steady supply of income to add to the Bitcoin investment helps the investor to always stay ready when there is a good opportunity to acquire more Bitcoin during the bearish season just like what we have now and having your money saved in Bitcoin and a job that gives you money in Fiat can easily help to make Bitcoin purchase faster because you don't sell to rebuy when the bitcoin price is low.
