Talked to a normie friend today.
He said, “BTC is about to die. Saylor will lose big again, just like the dot-com bubble.”
Curious, I asked why he thinks so.
His answer?
He read an article about quantum computers and is now convinced that once they’re fully developed, they’ll crack Bitcoin.
I honestly laughed. It’s crazy how one random article can completely change someone’s perspective.
I told him.
Quantum computers are not some magical switch where, once turned on, they drain everyone’s BTC and the network collapses overnight.
The actual concern is more nuanced.
Bitcoin uses ECDSA (Elliptic Curve Digital Signature Algorithm) to derive public keys from private keys. A sufficiently powerful quantum computer running Shor’s Algorithm could, in theory, reverse this and derive a private key from a known public key.
Yes, that risk exists.
If such machines are built, older wallets like Satoshi’s are more exposed since their public keys are already known.
But modern BTC addresses are different.
Your public key is hidden behind a hash and only revealed when you broadcast a transaction.
At that point, your transaction enters the mempool (a waiting room for transactions).
For an attack to succeed, a quantum computer would need to:
intercept your public key → derive your private key → create a competing transaction with a higher fee → and get it mined before the next block (~10 minutes).
That’s insanely difficult with current and near-term tech.
So how close are we?
To actually break ECDSA, we would need a Cryptographically Relevant Quantum Computer (CRQC) with millions of physical qubits or thousands of stable logical qubits.
Most experts estimate we are still 10–30 years away from that level.
And in that time, Bitcoin Devs won’t just sit idle.
We will likely see protocol upgrades and quantum resistant address schemes introduced well before this becomes a real threat.
TL;DR:
Yes, the risk is real.
No, it’s not unmanageable.
Keep buying the dips. 2026 is for accumulation.
