While storing bitcoin and earning it at a cost increase is very beneficial and there is no doubt about it. Investing in bitcoin is now quite safe. However, when it reaches a significant cost, investing in it, as I believe, will be more risky. If you only deal with holding bitcoin, there may come a time when he can again return to the cost of a hundred dollars. It can be ruined by great volatility and alarmists, who, with the slightest negative information, will sell their bitcoins, which will have a high price. Now it is better to periodically sell and buy bitcoins at a peak and lower prices, making good profits. In addition, this will help to stabilize the course.
