![]() We originally posted this article with data taken from before February 16, 2021. Since that time, we've seen record prices for Bitcoin and Ethereum come and go, multiple times. The difficulty of mining has steadily increased, and potential profits have trended downward over time. Currently, Bitcoin sits at around $38K and Ethereum is at $2,700. That's about a 30–35% drop in value since early December, 2021. Longer-term stability tends to be at lower profit levels than what we saw in early 2021. Eventually, the difficulty of finding a block increases, or the price drops, either of which will drop the rate of return, and miners stop putting lots of money into scooping up GPUs. Ethereum difficulty (opens in new tab) initially peaked in May, then declined until late June (no doubt helped by China's crackdown on mining), but has been on a steady upward climb since then and is nearly at 13,000 TH/s. Ethereum also has plans to shift to proof-of-stake (no more mining) in the first half of 2022, however, so GPU miners may soon have to look elsewhere. ![]() That brings us back to the matter at hand. Lots of people still want to know about mining, how it works, and how much they can earn doing it. We'll answer those questions as best we're able, and bring up other concerns and related information that you might not have considered. Hopefully, by the end of it all, you'll be better informed. The easiest way to get started at mining is with NiceHash. NiceHash launched in 2014, right around the time of the first major spike in cryptocoin mining (second if you want to include Bitcoin's initial "surge" to $32 per BTC in 2011). Prior to NiceHash, getting started with coin mining was more complicated - as we'll detail below. NiceHash has greatly lowered the barrier to entry, and it gets rid of some of the worries about what coin(s) to mine. Bright enough for audience note taking.You effectively lease your PC's hashing power to other users, who get to choose what to mine, and you get paid in Bitcoin. Slightly dimmed, window blinds leaking some light.īright ambient light: Windows open during daylight hours, lights that cannot be dimmed like in an open office settings. Some ambient light: Some additional light in room. Low ambient light: Little to no light entering room. ![]() * Controlled Lighting: If you plan to use your projector in a room where there are no windows, such as a basement, or if you use your projector primarily at night, any of today's projectors will provide a bright image. Our new Black Diamond SI Screens' proprietary screen material is able to reflect the light from your projector back with so much potency it actually increases the contrast ratio of your projector by more than 300%, enabling you to use the projector in a well-lit space.īut for those looking to purchase a projector, read on to learn how many lumens you need for your presenting environment. Below is a fast and easy reference for you to use to help determine how bright a projector you need for business, home theater, house of worship and education environments.Īlready invested in a projector, but wish it was brighter? Fear not.
