assuming scrptt hashrates stay constant thats six months roi not terrible
Which would be an insane assumption, Scypt hashrates haven't been even CLOSE to flat for a very long time now.
They haven't been as bad as that big jump in December 2017, but the average this year has been about 2% per difficulty period.
With cheaper miners I would think it goes higher or at least, it would go higher than if the miners were expensive.
The other bigger risk is that this is on 28nm. If a 16nm appears, it might be 3 times better, as how s9 is 3 times better than s7
Innos A4+ is 15-20% more efficient but is on 14nm node. So, if bitmain comes up with a 14nm l3 in future, it will be alot better i think. I really hope one does not appear soon though as it would be bad for L3+ owners.... but a 14nm L3 would possibly have no possible competitor that comes close to matching it.
Just my 2 cents
I'm beginning to think 80/20 that the Bitmain 1.5gh unit @ 1,300 watts exists. Thus the 'fire sale' of old stuff with/coupons...and likely they will 'announce' sales to us at the end
of Summer with the result of (likely these overpriced units) will hit us folk say around October 2018...
*THE KICKER IS* Bitmain will have these puppies in hand and likely run them full out (only game in town) from say May 1st to 0ct 1st being "mainly' the sole source of say
LTC difficulty rise of *guess* about 20-30% (worse case)...again I'm just guessing and IMHO.
But, even Bitmain, with these units, is going to have to see a pretty good increase in the price of scrypt-pow coins for this to have any 'validity' or they will simply
be as *skunked* as us 'regular folk', by the first of the year, IMHO. The difficulty increase waits for NOBODY...small/medium/or large without the price of coin being a factor.
ONLY good thing is IF you are a 'hobby miner" and can afford to 'eat' your electric say out of your JOB income...I'd do that on the bet of the LTC halving in April 2018 for LTC.
It is something to do, keep your eye on, and a 'modest' bet in my view...as to us larger miners...with data halls, etc...it may just be elec to LTC to USD and mostly back to Elec
oranges to oranges ..if the price goes sideways and difficulty surpasses price. I could eat a couple L3+'s in the basement and eat electric price on the April 2019 halving of LTC
...as my 'angle' on hobby miners...AS to such a bet for data hall mining or the 22 Bitmain units I have (even if month to month rent) ....well....
Such a bet would not be easy ..if above 'ugly scenarios' came into play and 'thwarted and struck me down' the other say 18 Bitmain Units .NOT in my basement..in my
new found 'hobby' mode...at that point in time..I suppose I could make a 'wall of
shame' out of .18 miners would make a 'formidable fort' to playin....but not a lot of wiggle room with data hall electric and fees...compared to a hobby miner betting some elecric
and HODL mode for next years April 2018 LTC halving...(Bit mining is great, but when the beast is pretty and big...but you got to feed the beast or it feeds on you!)
whatever, bets are made...time to ride the tiger
