In theory yes. If suddenly all crypto investors decide that bitcoin is useless or if a fatal flaw that no one has even thought of is discovered it could go to zero. But the chances of this happening are very slim. Bitcoin will always hold value because there will always be enough people who believe in the narrative of a digital store of value with superior attributes to gold. A common way to think of bitcoin's value is to compare it to gold. Gold has a market cap of ~11 trillion. If you include gold that is un-mined then we are talking about $15 Trillion. Bitcoin, on the other hand, has a market cap if $300 billion. According to this logic bitcoin's price should be around $500,000. If people were to accept bitcoin as a store of value and kept 10% in bitcoin and 90% in gold then bitcoin should be worth around $70K.
