The intelligence of the investor depends on his decision when to sell or buy. The purpose of investing is only to get a commensurate return, for investors who have held Bitcoin for the long term it is a good idea to sell some Bitcoin when it is traded at a high price. Price fluctuations that always play a role in Bitcoin's journey can be utilized to buy back when Bitcoin is trading at a cheaper price.

For small scale Bitcoin holders, they can also take advantage of the price increase to sell Bitcoin, the profits obtained can be reused to buy more Bitcoin at a cheaper price. Investing in Bitcoin is not always measured by how long you are able to hold Bitcoin, but you must be able to prioritize the initial plan when investing. Ideally in my opinion, when the price is high, sell immediately and buy again at a cheaper price.
