Just dont mind the change of price from time to time and think of the result long term if you keep holding your Bitcoin. Price and dump is normal when we talk about crypto and even stocks, Bitcoin has a limited supply so the longer you hold the higher the price it can go. What i mean is since it has a limited supply whatever happens now in the price and dump of the coin just think of the longer term when the supply reach its max what would be the price of Bitcoin then? So i suggest that just hold your Bitcoin.
