Wow, at $3-4K per miner, that's going to take over a year ROI, especially with the difficulty going up each month. And if BTC keeps falling, it's going to take even longer! People been snatching up miners on ebay for over $4K because BTC was skyrocketing to $20K! Well, it's dropped a lot since it hit the high. Just last month the S9 was under $1500 & the A741 was under $1K and BTC was over $8K; so people buying new miners then could still make over 200% ROI in a year even after deducting power costs. Now that's all changed with the miners doubling and tripling in price and BTC falling. So people are going to reassess whether it's still profitable to buy a miner or not. Though you'll still get that 1 in 10 who'll buy at the high end and at any price!
That's why the companies selling the picks and shovels for digital gold are making out like bandits; just as the people who sold them to the miners back then in the 1850s gold rush.
eBay pricing on miners doesn't count - folks ALWAYS try to gouge there, and far too often get away with it due to folks with more money than sense.
Most miners are BADLY spoiled, an ROI of less than a year is AMAZINGLY FANTASTICALLY GOOD when you compare it to most things you can invest your money into.
Tradeoff is that it IS higher risk than most of those other investments.
If Bitcoin stays above $12000, an 821/841 or S9 should easily achieve ROI in a year at the $3000 level (presuming the S9 don't lose a hashboard or die) if you have a SANE electric price to mine with.
Folks paying over 5c/kwh are killing THEIR OWN chance at ROI if they insist on mining Bitcoin itself through excessive overhead cost.
). I really want to buy a higher quality product from a good distribution network, I'm hoping price is right and I'll put my order.
