I am not investing in BTC. I am investing in any way to make dollars. I have many investments. This one happens to have something to do with BTC but what it does is generate dollars.
Wow OK now I think I understand why some people are paying a premium for miners that have no way of having positive BTC ROI.
Any time you "invest" you are trading the value of one thing (USD) for the value of another thing (BTC via mining) with the prediction that the second thing (BTC) will increase relatively (to USD) in value over time. So when you buy a miner you are investing your USD into a predicted amount of BTC you will receive in a future time period. If you don't agree with this basic fact then there's no point in continuing the dialog.
