When will Bitcoin become worthless? Or even go to zero?

- Satoshi Nakamoto's massive sell-off: Satoshi has a lot of Bitcoin, and if he suddenly starts selling one day, the market might panic, and the price would definitely plummet. However, many people are already using Bitcoin and many others are optimistic about it. Even if the price drops, some might take the opportunity to buy in at a low price, so it's unlikely to go to zero all at once.

- Capital controlling hash power causing destruction: If large capital like BlackRock controls most of the Bitcoin hash power and then conducts a 'double spend' attack, essentially tampering with the ledger, it would indeed cause everyone’s trust in Bitcoin to collapse, and the price would crash. However, Bitcoin players would certainly not just stand by; they would find ways to protect Bitcoin, so it may not necessarily go to zero.

- The emergence of quantum chips: If quantum chips become powerful enough to crack Bitcoin's encryption technology, then Bitcoin's security would be compromised, and people would definitely be reluctant to use it, leading to a loss of value. But currently, quantum technology has not developed to that stage, and Bitcoin developers are also working on countermeasures, so there’s no need to worry about it going to zero anytime soon. Speaking of which, recently Dao Ge is quite optimistic about Musk's little puppy PUppIE.s., with over 16,000 Ethereum wallet addresses, and the market capitalization is still low with huge potential. Interested brothers can set up an early position.
