Four questions about Bitcoin

Signal21 Editorial Desk ·

Some questions about Bitcoin come back in every market, calm or falling. Here are four of the most common, answered as plainly as the evidence allows.

Does the four-year cycle still hold? The idea rests on a rule written into Bitcoin's code: the halving, which cuts the reward paid to miners in half roughly every four years — every 210,000 blocks. Less new supply, the theory goes, and a peak follows. On paper it has held: the 2012 halving preceded a top in late 2013, 2016 preceded a top near $20,000 in late 2017, and 2020 preceded one near $69,000 in late 2021. The 2024 halving was followed by a record around $126,000 on 6 October 2025. Each peak landed roughly 12 to 18 months after a halving.

But four cycles is a pattern, not a law — a coin that lands heads four times has not proven it always will. And the mechanism is weakening. Each halving is a smaller supply shock than the last: in 2012 new issuance fell from about 25% to 12% a year; in 2024 it fell only from about 1.7% to under 0.9%, and 2028 will dilute it further. Some now argue the cycle is finished outright — Michael Saylor wrote in April 2026 that the four-year cycle is dead, set now by institutional flows rather than the halving calendar, and a large Bitcoin fund published a note under the same title. Others say it is merely later or milder. No one can settle it from inside the cycle. The mechanism is real; treating it as a clock may be the trap.

What happens if you lose your seed phrase? Holding Bitcoin yourself means being the only person responsible for it. The backup is a recovery phrase — usually 12 or 24 words — that can regenerate the wallet on any device; drop your phone in a lake and the coins are still recoverable from those words. But there is no counterweight: lose the words and your device access, and there is no reset, no support line, no one to call. The coins are not stolen — they are simply locked away for good. Chain-analysis estimates put 3 to 4 million bitcoin as lost forever, mostly to mislaid keys — close to one in five of the 21 million that will ever exist. Hence the phrase the field repeats: not your keys, not your coins.

Why a block every ten minutes? There is no bank keeping the accounts. Thousands of computers worldwide hold one shared ledger, and roughly every ten minutes they gather recent transactions, check that no coin is spent twice, and append them as a new block — which is what makes a payment final. The ten-minute figure was a design choice by Bitcoin's creator, not the output of an equation. A new block has to be announced to every computer on the planet, and that takes time; if blocks arrived every ten seconds, a second machine could find one before the first had finished propagating, splitting the ledger into rival versions and favouring the best-connected. The interval must stay comfortably longer than that travel time. The network holds the average steady on its own: every 2,016 blocks — about two weeks — it adjusts the difficulty up or down so blocks keep arriving near ten minutes apart, whatever computing power is plugged in. It is an average: some blocks come two minutes apart, some forty.

Can Bitcoin go to zero? A large crash is not the same thing. Bitcoin has fallen more than 80% before and could again — that has to be accepted before holding it. But zero means something else: the entire network abandoned, no miners, no users, no buyers. The distance from that is worth measuring by what would have to switch off at once. The computing power securing the network is around one zettahash per second — billions of dollars of machines and electricity. Roughly 24,000 reachable computers run it across more than 150 countries, and many more stay hidden. Bitcoin has been declared dead hundreds of times since 2010, by newspapers and Nobel laureates alike, and is still running. The committed capital has never been larger: a single BlackRock fund holds tens of billions of dollars of it, one company alone holds more than 800,000 coins, and some governments have begun to accumulate. None of this makes zero impossible — a flaw in the code or a major technological shift are real risks, even if they recede as the network grows. It would simply require abandoning the most secure state the network has ever been in.

No one can time the cycle or foresee the future, which is why trying to guess the exact moment to enter and exit is where many go wrong. Bitcoin is best understood as a long-term holding — one whose owner is never forced to sell. This is general market information, not a recommendation to buy or sell any asset.

  • Whether the next halving in 2028 still precedes a peak, or institutional flows fully sever price from the calendar.
  • A sustained collapse in hashrate or node count that made the "zero" tail less remote than it now looks.
