I tell you something: Mining for Cryptocurrency requires a lot of computational power, a lot of cooling (Not that a liquid cooler ought to fix it) and a top of the line PSU to make it all run, yeah.
This whole mess started in 2017, when a cryptocurrency named Ethereum (ETC) started to gain popularity and rise.
Ethereum became the craze, and I mean it! a single ETC was worth 850$, that’s a lot of cash, well worth the investment of a GPU.
Then we get a whole army of aspiring miners buying every cryptocurrency in sight, and a shortage happens, and prices start to rise like crazy, and I mean it. (In early 2017, the price for a GTX 1050Ti was around $150 USD, not too long ago, it was at over $300 USD, more than double the previous price.)
Basically the entire line of GPUs, ranging from the 1050ti to the 1080 get on shortage, prices increase and everything becomes crappy, eh? This is likely due to the fact that AMD Cards, which are much better for mining, became inadequate in the supply department.
Now ETC is 390.45$. (At the time of this writing, of course.)
Now it’s 2018 and we’re talkin’ about Bitcoin mining.
Unlike ETH, you need a ton of power to mine BTC, I mean a entire room full of GPUs, and now we got companies that especialize in mining GPUs!
Then to solve the issue AMD and nVidia start making mining cards, supply normalizes, and retails now limit a card per buyer.
The improvement in supplies seems to partially stem from news of the imminent release of the first ever ASIC miner for Ethereum, which would render mining Ethereum on GPUs almost entirely obsolete. Ethereum is still one of the most popular cryptocurrencies. (Still not as high-valued as BTC.)
And that’s that. I think this whole thing was particularly good for the market, cause now retailers know how to deal with this crap and the manufacturers are making miner cards, making everybody happy.
