Life is short and one, so I do not agree with the statement that selling Bitcoin for pleasure should be completely avoided. An investor should try his best to make life beautiful and enjoyable. And wealth is not just to accumulate it with difficulty. Therefore, it is not unreasonable to sell Bitcoin to buy a necessary car, travel to spend time with family, or improve the quality of life.
However, it is important to me not to sell Bitcoin for low-quality investments because it is not wise to go into risky or weak investments by selling Bitcoin for the long term just in the hope of making more profit from some other investment.
If you are making investment to sell it for pleasure, then your decision to invest in Bitcoin was not given proper thought. The philosophy of life being too short so we can live lavishly and chase enjoyment has made many people not to achieve anything, whatever money that come their way will be spent without accountability. So, a Bitcoiner selling Bitcoin to go spend the money carelessly is not doing the right thing. Selling Bitcoin should be systematic and organized in a way that it will not make the investor run out of Bitcoin.
