Now a days we sometimes seeing the price of Bitcoin falling along with others also falling.
At that time if I have Bitcoin then what should I do ?
Should I sell or hold?
Of course you have to hold it, and if you have enough money I suggest you also buy bitcoin because it's a good opportunity to buy bitcoin when the price is falling. selling bitcoin when the price is low it will hurt you because people will usually sell bitcoin when the price is rising so they get lots of multiple profits and even though you are waiting for a stable price for a bit the price of bitcoin will definitely go up. Long-term investment will be better if you want to do it.
