This question is already expected from a newbie as one is not knowledgeable and used to see the market having price fluctuations most of the time. But when we talk about bitcoin, knowing it’s the most prominent and the one that dominates the crypto market, it’s hard to see its value dropping into zero. Although bitcoin is also not stable, but knowing that it had survived more than 10 years of battling with a lot of attacks, that one proves that bitcoin will not be easily become useless in the end.
Well, the OP is obviously and indeed a newbie in this kind of discussion and seriously didn't bother to do some research before starting a thread here in this forum. Bitcoin has a chance to drop to flat zero, yes, but that possibility is really like a razor-sharp type of slim. Even if the whales will work altogether, they cannot possibly sink the bitcoin to have a zero price easily because there are other holders as well who holds numerous amounts of bitcoins as well as those wallets who have been buried or forgotten.
