My hashrate also dropped a little bit in the last 24 hours, but the the problems is that the profit is only half of the normal level. It is strange. I will watch for one day to see what's going on?

In the past 24 hours, my profit is only 0.00729501 BTC with 77.4 MH/s 24-hour Average. Current profit rate is 0.000182 BTC/M, it should be 77*0.000182 = 0.014014BTC. What I actually got is only half. Anyone has the same problem?

dannyspk, did you get your deposit credited to your account? I unfortunately send the ltc to my old address and did not know notice that the address changed. I check the address I used and it is automatically withdraw after I deposited to it. But they are not credit to my account.

My internet connection is 25M download, 5M upload. Bandwith requirement for mining is very minimal and should not be a problem for US miners. Here is a little more details:

Last 24 hours

wafflepool: 0.20 BTC
CleverMining: 0.18 BTC
f2pool: 7.5 LTC ~0.13BTC

the miner in Coinotron pool --> wafflepool
miner1 in f2pool --> Cleverming
miner2 in f2pool stay

 I will up date my result later.

Coinotron and f2pool has almost exact profit based on my payout during my hosting in JTMiner. I prefer f2pool for the graphic hashrate display.

Here is a screenshot this morning for my 2 miners in f2pool. Average hashrate around 88-89M, most time above 85M, very stable:

After careful comparison, I decided to buy three 90M A2 terminator from JT Miner 2 weeks ago.  

Because I was out of town after my payment, JT Miner kindly hosted my 3 a2 terminators until I came back with a daily hosting fee of $4 for each miner, very nice and sweet deal. So they set the miners running for me once they confirmed my payment on May 28th and I got 328 litecoin in total during my vacation.

I was back last weekend and they shipped my miners to me yesterday (June 9th, Monday) using overnight service so that I got it this morning. to my surprise, it is unbelievably easy to setup the miner:

unpack → plug in ethernet and power cable → switch on → bingo! my 3 goose starting laying coins. → go to web UI for miner config and realtime running status  → go to pool web site to check the actual coin my goose laid

That’s all I did. Now 3 goose are laying litecoin for me cheerfully, roughly 1 litercoin per hour right now.

Overall impression: very stable, speed fluctuated around 88-89MHS, pool reject rate between 0.18% and 0.4%, power consumption around 830W. Very good and I am very satisfied with it.

Please note that general US household has most of lighting circuit line with 15A, so I have to put the my 3 miners to 3 separate lines.

Let’s see some photos:

Realtime status: red circle is average speed and rejected number, rejected rate is 112/54164 = 0.21%, excellent.

Total payout from coinotron is 107.51, balance is 2.05, so total revenue before yesterday 11am is about 327.95

This is my brief review of my three 90M A2 terminator from JTMiner and I would keep it update when I get more familiar with them. Good to know that the litecoin mining total hashrate dropped from 350G yesterday to 290G now.

Agreed. 1T only 900W, ants can't beat it. Of course if you have free electricity and love the noises, that's different story.

From the beginning it is suspicious for bitcoinultra. They push a product into market when it is still in development stage. Before announcing the product, they should at least have a small  batch of rigs tested fully at least one week. development/lab <--> test in real situation <--> product in the market. Too much uncertainty from lab directly to product. Let's pray this will not turn out as another scam.

The price is very attractive but also very suspicious. I checked the 28nm chip prices from bitmine, 40 chips itself = $2800 ~ $3500. If you sell your whole rig for $3250, I could see no profit or a loss even though you copy the design from others and spent $0 on the R&D. There must be some hidden secretes here. Caution: focusing on fact, not the promises.

Hi Colorfulbit, do you have website for detailed information? If this is true, it will be a extremely sweet deal.

I do not think the btc will replace credit card, but complimentary to it, which is a good to the consumer. For instant transaction, btc is not the right choice.

anything goes online is not 100% safe. Anyone heard of the hardware btc wallet?

good video,  but be careful, btc is not for everyone, especially ones with weak heart.

let's pray the btc go up to 10K!

here is the website to for LTC calculation

proof?

Practically, this will never happen in btc mining. some alt coin maybe.

at the current btc price, investing mining is hard to make profit. if the btc price could rise to 1k or 2k, the calculation is different.

0.02, no way. maybe possible under special situation which has government subside.

if US ban BTC and other countries such as from Europe, Chian, Russian do not, what will happened?

I think you even do not know who you are selling your bitcoin to. Just like in stock market, you sell you stock and whoever bought it, has nothing to  do with you.
