Holding bitcoin is not always good, especially for a long time because we never know what will happen to bitcoin and the price too. On the other hand, if you holding it not for a long time and you keep checking the price, you can make a money on it. I'm not saying holding bitcoin a long time is not good but if you look at the price right now, do you think the bitcoin will increase again soon ?
If the past performance is any guidance, the price of bitcoin will rise in the long term.
