It all depends on the one's approach towards the bitcoin and one's need & expectation from the crypto market whether to start saving the bitcoin for the future purposes or should we spend bitcoin which we earn from the trading or mining sources. Some people prefer to save the bitcoin for longer-term investment which will be useful for their retirement or for their children's savings, which even i am following. And some people earn bitcoin just to support their monthly expenses and according to me, both the points are the proper and right thing to do.
I totally agreee with your view point . It depends on how you want to use bitcoins. You have the option to sell it and get cash (dollars or rupees) back or you can save it and get the profits. Again when the market go down you can buy more bitcoins at lower rate.
