Charles Hoskinson, the founder of Cardano, has raised concerns about Bitcoin's plan to protect itself from future quantum computers. Bitcoin's proposal, called BIP-361, aims to make Bitcoin safe from quantum attacks. But Hoskinson says this plan cannot protect about 1.7 million Bitcoins, including many coins mined by Bitcoin's creator, Satoshi Nakamoto. These early coins do not have the new security data needed to prove ownership under the new system. Because of this, these coins might be stolen by quantum hackers or become unusable forever.

Some experts say the quantum threat is real but far away. They believe current quantum computers are not strong enough to break Bitcoin's security, and there is enough time to fix the problem. Others say the problem might take 20 or more years to become serious, and some coins can be moved safely today without changing Bitcoin's rules.

The main issue is what will happen when powerful quantum computers arrive. Fixing this might need big changes to Bitcoin, which is hard because Bitcoin is designed to resist changes. So, the question is: Is this a big problem now, or something the crypto world can solve before it becomes dangerous?
