Bitcoins <\/p>\n
Quantum computing is moving from theory to practice, and a
\nnew whitepaper warns that major cryptocurrencies need to react much faster than
\nthey have so far. The study shows that once a powerful enough quantum computer
\nexists, it could break the cryptography behind Bitcoin, Ethereum and other
\nchains in minutes, putting both long\u2011dormant and active assets at risk.<\/p>\n
