The hell you talking about? I've reached ROI on multiple miners that I purchased last year(think september/october).
It's all about making smart decisions vs making stupid ones...reinvest.
Compound interest is where the real money is made.
Every gambler knows
That the secret to survivin'
Is knowin' what to throw away
And knowin' what to keep
'Cause every hand's a winner
And every hand's a loser
And the best that you can hope for,
is to die in your sleep
Although people unwilling or incapable of running their own probability calculations won't necessarily be making a majority of smart decisions.
GPU's might be a better profit to electrical cost ratio, but they require a much higher initial buy in...and a little bit of technical skill to get the build off the ground. You can buy a "turnkey" asic for the same cost as a single decent GPU...and that isn't counting the additional hardware to make the GPU generate income.
As long as there are locations with free power...all mining devices have value.
That was last year when diff was MUCH lower,my margins for ASICs were not so good due to 13c kwh power & quickly rising diff...........
Well,as for my mining GPU's,I had to buy the vid cards but the 5 PSU's I bought along time ago when BFL & Avalon miners were the rage (2012-14),so they were just hangin around
That "additional hardware" is free if you have half a brain
Used dual core cpu's,old 4 gig ram,old mobo with at least 1 PCIE slot (found a few with 2 slots) & crappy case big enough for the GPU.
I also have rigs with no case
I started with a few 6950's & 5870's & a 7970,all those profits went to new cards,380's mainly.
My GPU's have returned almost 4 times their value since 8 months ago,has your ASIC hardware done that??
And I have a 3 year warranty on my cards,your Bitmain/Avalon has what?? and I can sell these cards at almost what I bought em for & get my investment back if anything goes wrong
