Although cryptographic hash functions, such as the SHA-256 used in Bitcoin, are **quantum computer **reliable, the Secp256k1 encryption method, like all **ECDSA algorithms** is vulnerable to quantum computers. A powerful quantum computer will be able to destroy Bitcoin with its current technology.
Humanity currently does not have the technology necessary to create a quantum computer large enough to attack Bitcoin keys. It is not known how quickly this technology will advance; however, cryptography standards such as ECRYPT II tend to say that **Bitcoin's 256-bit ECDSA keys are secure until at least 2030-2040.**
**GPU cryptocurrency mining rigs** are the absolute favorites for people looking at how to build a mining rig. They’re definitely among the most popular crypto farming methods out there – anyone from a single miner to a corporation, possessing a whole mining farm, tend to use GPU rigs. GPU mining rigs utilize graphics card GPUs to mine data from the blockchain. They can be dedicated or simple miners – dedicated GPU mining rigs are built for a solemn purpose of cryptocurrency mining, while simple miners are devices that are used for other intents and purposes, doing crypto mining only on the side (i.e. desktop computers). People love GPU mining rigs for their usefulness – these rigs do the job and they do it with grace. Naturally, to get the best results, you would have to use the maximum amount of GPUs available, but even with the simplest of rigs, a result would be noticeable.GPU mining rigs do have a couple of downsides, however, that a person looking on how to build a mining rig should know. The biggest downside is its price. Graphics cards tend to be quite expensive (or very expensive, if you’re aiming for the best of the best), so the initial investment you might have to make could be somewhat significant. They also require maintenance – a lot of cooling, plenty of electricity to fuel their power, generally looking after and taking care of, etc.

The mine we visited was just one of six sites owned by a secretive group of four people, part of a colossal mining operation that, as of our visit, cumulatively generated 4,050 bitcoins a month, equivalent to a monthly gross of $1.5 million as of 2015. Since then, the cryptocurrency mining world has become even more extreme.

**LBRY is a decentralized, open-source protocol that is controlled by its users. LBRY facilitates a similar experience to services like YouTube, Netflix, and Apple TV... but LBRY is entirely decentralized! Services like YouTube are centralized platforms controlled by a single corporate entity. These companies can change the rules unilaterally, as well as censor content to appease authoritarian governments or corporate partners. LBRY can never unilaterally change the rules on publishers or consumers, making it dramatically trustworthy.**
The aforementioned video providers—along with P2P file-sharing clients like BitTorrent and IPFS—also do NOT support direct payments to publishers for the content or data they create and publish to the network; LBRY does, and LBRY also creates market incentives for data to be as widespread and available as possible!
LBRY also supports the sharing of free content, but if you are earning money from your videos on YouTube right now, you are likely familiar with the recent controversies over videos being “de-monetized” for containing content unfriendly to advertisers. It’s no surprise that YouTube caters to advertisers, because those are its ultimate customers.
LBRY is not an ad-driven media service. In fact, it’s not a traditional media service at all. LBRY is an open protocol that allows you to publish your videos to the network at no cost to you and set a price per stream or download. Because LBRY is a protocol and not a corporate store, there is no approval process for content to be listed and no authority that can “de-monetize” your videos. That’s between you and your fans.
With LBRY, pricing is completely at the discretion of the creator and up to 100% of that price can go to the creator. (Compare this to iTunes’ fixed pricing tiers and 30% cut of every sale.)
Because LBRY uses digital currency (a la Bitcoin), creators can accept micropayments for every view without worrying about credit card processing fees. Or a studio could use LBRY to distribute a theatrical release to independent theaters and charge thousands of dollars per download. The only constraint on pricing is what your viewers are willing to pay. (You can also set your price as zero if you are not looking to monetize your content!)
LBRY also allows users to automatically earn rewards in exchange for contributing bandwidth, disk space, or processing power to the decentralized LBRY network!
What’s more, you can share content of any type – video, music, ebooks, images, podcasts – all on the same platform!
