As per my knowledge, Some investors invest in bitcoin when the price reach to 20,000$ but now price is hardly more than 10000$.
Should they loose their money?
But still investors are invest in why ?
At that peak they invested because it was sure that the price will continue to increase and it was about to happen when some countries started their regulation and because of the fear of some investors they withdraw their money while some are waiting, and now they are investing more because those who sold now know that the price will go rise in the long term so they are buying and waiting for long time and others who already in bitcoin are buying more because they are the stronger supporters of bitcoin and they know that buying now is more beneficial.
