Only 10K Bitcoin at quantum risk and worth attacking, CoinShares claims

Most quantum-vulnerable Bitcoin sits in wallets holding under 100 Bitcoin, with CoinShares claiming it could take a millennium to compromise each one.

Digital asset manager CoinShares has brushed aside concerns that quantum computers could soon shake up the Bitcoin market, arguing that only a fraction of coins are held in wallets worth attacking.

In a post on Friday, CoinShares Bitcoin research lead Christopher Bendiksen argued that just 10,230 Bitcoin (BTC) of 1.63 million Bitcoin sit in wallet addresses with publicly visible cryptographic keys that are vulnerable to a quantum computing attack.

A little over 7,000 Bitcoin are held in wallets with between 100 and 1,000 BTC, while roughly 3,230 Bitcoin are held in wallets with 1,000 to 10,000 BTC, equating to $719.1 million at current market prices, which Bendiksen said could even resemble a routine trade.
