In investing terms you need to keep holding it and wait patiently for the good price, you dont need to sell it after you buy. Just like gold, it is more expendive in the future. You dont need to make rush but you need to wait. Wait for the coming better price in the future. Holding bitcoin in a long time is a good way to make money. It is so obvious in the question. So, it is better to hold.
Agree but to be honest when the panic selling wave comes in to the market picture, it is very difficult for an new investors to keep calm and stay with his holdings. It works like domino and thus price falls drastically. Ideally, if someone has bought bitcoins for the long term then he should not worry about short term market movements. I used to find myself in panic selling wave in first few weeks of my investing.
