I will pay $30 to whoever has written the best answer by noon EST on June 26. I will also consider paying something to runners up if they provide additional good info.
1) What are some good options for ASIC miners to buy, used or new? I have free electricity and therefore only care about price/TH, not power efficiency. I am mainly interested in non-bitmain miners because I don't want to support Jihan, but competitive bitmain options should also be listed. Focus is on Bitcoin miners, but if Litecoin or Sia or any other ASIC is currently way more profitable, I'd like to know about it. Which coins can be mined with ASICs either currently or in the near future?
2) I am about to build a new computer to play games on my Vive. What video card (and processor if those still mine anything well) should I include in my build in order to mine crypto when I am not gaming, with my free electricity? What are the best coins to mine currently, and is there a website that will tell me what is most profitable to mine right now? What kind of hash rates and profitability can I get with your recommended video card? I don't want to spend a lot of time screwing around with configuring crashy miners, like I had to when I mined several years ago.
In addition to plugging the hash rate into a calculator at current difficulty, based on your past experience or math, please estimate a few different scenarios of how profitability might change based on future price action and more mining power coming online.
