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.
it's all depends on situation of one person,but its a good idea if you're going save 60 percent of it and spend 40 percent or invest it. It's up to the person what he wanted to go with it , but it's better to be wise in our action so you'll will gonna regret with what you done.
