A lot of people still think quantum computing is something way off in the future, but honestly the pace of progress has been surprising. It’s moving faster than most of us expected.right now, bitcoin and most other cryptocurrencies are built on elliptic curve cryptography . The problem is, once a public key shows up on-chain, a powerful enough quantum computer could, at least in theory, reverse it and figure out the private key.
Now,i am not saying this happens tomorrow,but if bitcoin does not upgrade its cryptography in the next 3–5 years, the risk gets very real. Quantum hardware is improving step by step, and once it crosses a certain threshold, the current security model won’t hold up.
We’re talking about the world’s fifth largest asset here. If it doesn’t adapt, the idea that its security could collapse almost overnight and bitcoin price will go to zero.
If you're just about Quantum Computers, let me tell you we're still off by 10 years before we get quantum processing power that can crack Cryptocurrencies and pose Tremendous Risk to Bitcoin, however it's best to be safe, always invest in a large diversified Portfolio and keep your coinz in a ledger or a physical/Cold wallet, there will be time for bitcoin to be in shambles, but knowing people, it'll get back up very fast, back on its' feet, unless there were to be a third impact like Satoshi's address being milked, or third parties like (blackrock, Vanguard, Tesla, MGSN, Etc) manipulating the markets (which is already happening by the dozen bundles), Bitcoin is by People, For People, we should not let Major Corps hold a large sum of it, or else we're talking Monopoly. today they hold around 16% of the total Bitcoin Vol there is (with other corps not mentioned here ofcourse), If they decide to bond and sell at once, bye bye bitcoin for a couple months, blown back 10 years, probably sit at 40K, but ofcourse most people will see this as an opportunity to HODL even more Bitcoin, which can be very profitable in a couple years time.
another thing that can be risky for Bitcoin is probably non-adoption, if people decide to put their money elsewhere, we're talking shorter daily trades, lesser volumes, but for that to happen we're looking at a new cryptocurrency that has better utility and safety than Bitcoin, with the variable of how many coins there is as a maximum supply
