According to my perspective none of the real holders of Bitcoin have lost so far. Those who get loss were not good holders. We have seen the halving of Bitcoin in the last few days and hopefully if the market situation improves we will see the new ATH in the future as well. So it doesn't matter in which price you buy bitcoin, they will not lose what I believe. Those who have not yet purchased Bitcoin this is the right time for them to purchase it and should be hold for long time.
