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 ?
Most of the bitcoin investors know if the bitcoin experiencing down fall, so some of them invest here on bitcoin to help the bitcoin recover and rise again. Some of them quit investing here on bitcoin because they think the bitcoin being bankrupt they think they cannot earn if they continue to invest here.
