So, I regularly keep an eye on eBay to try and spot trends in electronics sales happening and I believe I've found one. I have a RX 480 4GB graphics card I bought in March for about 180$ US. Well, the cheapest on eBay at the time of this post is 315$ ..... the prices are the same between the 4 and 8GB models in some cases. Soooo I wanted to see what's causing this massive spike in pricing and I believe it's Ethereum mining. It seems the new(ish) cryptocurrency has experienced over 1000% in value growth over the past month. Now people are hopping on the mining wagon again, and prices on AMD GPU's have risen because the most effective way to mine is to run the hash algorithm through the GPU rather than CPU. Apparently AMD GPU's perform better so ...... Anyways, I just had a few fleeting questions I thought I'd throw out here, and see what folks thought. 1. I read something about a Bitcoin "split" affecting the value of Eth. What is this "split", and how would it impact another cryptocurrency? 2. How bad is mining for a GPU? 3. With the way Bitcoin took off, would it be worth it to invest in a mining rig now? 4. Anyone else fool with Ethereum?
