4 Reasons Bitcoin might fail according to Nic Carter

His 4 reasons:

1. Bitcoin becomes de facto proof-of-stake. Proof-of-stake wouldn't be added to the code, however, large exchanges would end up running their own mining operations to keep minting new blocks because the 'security budget' (block rewards) would become too little to sustain a large ASIC industry. Meaning: not enough reward fees per block (and the newly generated coins would be too few because of many halvings).

2. Some huge bug. Would be recoverable, but need to restart the ledger to a prior point in time.

3. Quantum threat. Nic believes we might be underestimating the pace at which quantum computing is moving. Elliptic curve signatures as well as Schnorr signatures would be imperiled. Coins with revealed public key addresses are quantum vulnerable (e.g. Satoshi's coins). If quantum supremacy suddenly happened, the blockchain would need to be halted, updates implemented etc. Messy.

4. A good algorithmic stablecoin. With an algorithmic monetary policy that's more reactive to the economy, would allow for something more price stable.

He estimates the percentage chance of every threat in the 5-10% range, so about 25% in total that one of these end up happening.
