There are actually a few different ways a quantum computer can snap a blockchain.
For one, blockchain transactions are secured with digital signatures based on elliptic curve cryptography (ECC). ECC coincidently is also used on the internet to encrypt user data and website traffic.
However, ECC is not “quantum-safe,” according to Post-Quantum’s Cheng, meaning that a powerful quantum computer could theoretically decrypt user private keys and forge transaction signatures on their behalf.
“Once that trust is broken, that will be the end of cryptocurrencies,” said Cheng, adding:
“If you can no longer tell whether [the right] people are signing transactions to you or not, then you have destroyed trust. This cryptocurrency world is based on a distributed, trustless environment.”
True about stocks in general - the more volatility, the more being a “trader” offers opportunities.
Crypto are at a relatively immature stage with lots of volatility still, so if you are a trader, it can offer an interesting game.
What’s funny is that when you actually look over different periods that are more than just a couple of months, you will be surprised often at which investments made you the most money.
Limited supply, increasing demand. The halvening will happen next year, which will lead to a spike. (Last frenzy when it went to 18k was also before the halvening).
Crypto is being adopted more and more on a large scale.
Let’s not forget Facebook also wanting to enter the game with Libra.
China doing great things with NEO and Ontology and other coins.
Anyway, I am not a BTC holder, I hold and trade a variety of alts as they are even more volatile then BTC.
I am in Xtz, Link, Bel, Uni, Ont, Neo. Generally alt coins as the gains are larger than in BTC. Mind you, they are all tied to BTC’s movement. So BTC up is good for all other coins.
I bought into IOTA for 2¢ a piece, then came the great cyrpto surge of December 2017 when people bought everything for fun and IOTA went up over $5 a piece… Should’ve fucking sold as its hovered at 25-30¢ ever since
