Hi,

I am doing a deep research on all the available mining contracts

Opened or in process of open accounts at :

1) http://cloudhashing.com/
2) http://www.bitcoinfrenzy.com
3) http://www.minerlease.com/
4) http://www.bitcoinhashing.com

If you know another operating or close to be operating contractors please let me know.

Also I am starting  a website to publish related info and the experiences I get with each one.

All the best

They are liar :
they say:
Each contract gives 200MH/s of mining power for one year. It will generate about 1.1BTC in one year.

Nobody know how much BTC it will be after year? but I feel that it will by much less that 1.1

Wasn't the first set of minerlease contracts supposed to be initiated by now? With payments being payed out on the Sundays of every week?

Hello, its a little early to give to many details, but I have some killer investor comps planned.

Theres a little preliminary informtion at this thread; https://bitcointalk.org/index.php?topic=293098.msg3142446#msg3142446 (https://bitcointalk.org/index.php?topic=293098.msg3142446#msg3142446)

You're a newbie aren't ya?

"It will generate about 1.1BTC in one year". They aren't talking about actual money, they're talking about the amount of Bitcoins generated. The currency symbol for Bitcoin is "BTC", just like how USD is the currency symbol for "United States Dollar". So, they're not lying.

You sayin' BTC isn't actual money?
But USD is of course.  :D

Not to mention that 200MH/s will never generate about 1.1BTC,
not in one year, not in 2, not in 100.

bitcoinx dot com says about .25 BTC over 12 months

There is no accurate way to predict returns over 1 month, let alone 1 year. It cannot be done with any accuracy, this is the nature of mining!

Last months difficulty increased by near 30% each 10 days.
So prediction should be corrected :)

Good topic.. Thanks for creating the, :)

Most of the mining contracts that I know isn't good in term of price per GH/S.

Personally I don't like the causes most have like everything is covered unless their processor dies then the contract becomes null. Sneaky loophole.

Hey why not try the new trading platform that you can buy GH/s as shares. And then sell it for a profit + mined bitcoins while having the shares. The link is on my sig. Please check.

Instant mining by GH/s exchange (now sell/buy 1 GH/s ~ 0.18 BTC) on CEX.io (https://cex.io/r/0/otov4its/0/)
And futures contracts on Bitfury chips.

I have purchased one mining contract from byteminr.com & yesterday received first payout too  :)
but i am not sure whether its their goodwill payment or mining revenue.

They dont really seem to be a good investment, considering the trouble with the apparent delays on a lot of the HW your relying on someone else who is relying on a company to actually ship a product, and accurately report how many mining machines they bought....advice these days seems to be buy btc when the price drops a bit every now and then

Just use CEX to start out:

Cex.io (https://cex.io/r/1/Zeek/0/)

Spread your investments.

Only when the price stay on 0.1 btc... :P

The rise in difficulty is the number one factor by far. Difficulty will increase about 50% each month for the next year and that makes 1 GH/s worth about 0.18 BTC (and falling). If you are paying more than that, you are going to lose money.

Also keep in mind that paying significantly more for a 2 year contract over a 1 year contract is a mistake because your contract will hardly be mining anything after one year.

Add this one to your list of Bitcoin Mining Contracts

http://www.CryptoCurrencyInc.com


http://www.CryptoCurrencyInc.com now offering bitcoin mining hosting service starting at $10 per 1 Gh/s
works for 12 months.

You're a newbie lol. He is trying to say they haven't accounted for difficulty increases.

Are these bitcoin mining contracts even profitable at all?
Wouldn't the (potential!) profits be a lot lower than if you would buy and hold bitcoins anyway?

I'm currently trading on Mtgox and I don't think I could get the same kind of profits by mining.

With the dynamics of bitcoin how could these contracts payoff. Wouldn't mining contracts for litecoin be more profitable at this point?

Hi,

I am using the http://www.contractbtcminer.com/member site since july.

It is paying well.

Only post in newbie section about contract site.

Seems legit.

HI,

Last month I purchesed a mining contract that works in a method of re-investment fund. so when I started my contract was 5gh/s and at the moment my contract is 15gh/s. The idea of the website is that the increase of the difficulty wont be that affective on you.
I didn't write this post before I actually received any btc from this website.


So what I can say about them?

* they are paying every 15th and 30th of each month.
* they guarantee minimum  of 0.045 btc/contract/week
* their support answer emails very fast (most emails were answered in less then a day).
                     (it is hard to find all this information on the website, I managed to collect it all because I was curios and I sent many emails)
* they have very nice Affiliate program so here is my secret motivation to share with you this information. but hey if by sharing this information we both will earn lots of bitcoins then why not? right?
* they have 3 kinds of contracts:
Indefinite Contracts yes this is very abstract in a matter of time span but the idea is that it will go on as long as it is possible to mine (when there will be 21M btc in the world) or until this company will decide to disappear I have no way to check how trustful they are but they gave me first payment so it seems they are ok.
this contract is the best of their deals then they have decided to put a 5000 contracts like this as their limit this cost 1.1btc

1 year Contract unlimited numbers of contracts this cost 0.8btc

6 month Contract it is not yet availible it will be limited as well to 5000 to those who don't want to risk a lot this cost 0.5btc



so far they have kept their promisses with me and a friend of mine so if they will keep all their promises it will be maximum 22 weeks to recive one bitcoin with this contract. with every kind of their contracts the actually guarantee pretty high profit.

please if you decide to purches a contract write my member ID as your Affiliate. my member ID: ULIF8968


oh yes I almost forgot the link for the website: http://contractbtcminer.com/member

Thanks,

This post is suspicious. Like the one above, this is the poster's only post on the site. At best, someone is spamming the site. At worst, it is a scam.

This is why I think the site should be avoided:

According to this person, he bought 5 GH/s a month ago and now it is 15 GH/s due to the "reinvestment fund", but there is no way 5 GH/s can mine enough BTC to buy 10 GH/s in just a month. 5 GH/s will mine less than 0.05 BTC in a month and a one year 10 GH/s contract costs 0.80 BTC.

According to this person, the site pays a minimum of 0.045 BTC per week per contract (10 GH/s), but 10 GH/s only mines 0.030 BTC per week. They cannot possibly pay a minimum of 0.045 per contract.

According to the site, an "indefinite" contract (10 GH/s) costs 1.1 BTC. That is 0.11 BTC per GH/s, which is twice what cex.io costs, Furthermore an "indefinite" contract of 10 GH/s will mine less than 0.3 BTC, so you will lose 0.8 BTC on every contract.

Hi odolvlobo!

well that is right it was my first and only post on this site.
I tried to get some affilates from here. and this is because when I bought this contract it was after reading in forums such as this one about
contractBTCminer. I decided to give it a try and it seemed to be working fine,
so I decided to increase the payments by having more people on my affilante program.
about the 15 gh/s I have no idea where did you got the info that it is only 10 gh/s. on my profile in the website it was written "all contracts are 15 gh/s".

Anyway I hope your reply had scared people away. since last morning the website is down. I lost almost everything I payed them and some of my affilantes lost all they put. it was probably a scam, but I got scamed too  :-[



I'm interested to know how big is the scam... just since I bought the contract I know about 4 more who got scamed.
please, if contractBTCminer has scamed you too please write me an email with the story and I will try to create a post with all the details so others will have more information about those stuff in the future.

email I opened for this porpose: scammed.by.contract@gmail.com

here are the details of the domain:

http://whois.domaintools.com/contractbtcminer.com.

probably all are fake details... the phone is slovakia and the city is in Czech Republic. but if anyone have some more details please send them
maybe we could get enough details to catch the guys that are responsible for that scam.

thanks and hope we will never get to be scammed again!

Is this legit or a scam http://www.ebay.com/itm/261366727419

Scam or not, it is overpriced. It doesn't start mining until April and I estimate that the value of 25 GH/s in April is about 0.11 BTC.

what would be the best place to invest right now in mining?

Honestly, I don't think operators of Mining Contract sites would be running them if there was no profit to be made for them.

Buying your own mining hardware is better than renting hashing power from a third party company.

That's just my two cents (:

Is any news for this topic?

Its dead thread, no one updating anymore this thread

How did you find this 5-month old thread lol?  :D

it's a nice thread anyway, anyone tried hash.rentals?

This topic is a good theme.
So why not any news for this theme?

You also have the Butterfly labs mining contracts.
https://products.butterflylabs.com/homepage-new-products/1-gh-cloud-hosted-bitcoin-hashing-power.html (https://products.butterflylabs.com/homepage-new-products/1-gh-cloud-hosted-bitcoin-hashing-power.html)
I have bought 2 of them on 13 february, and still nothing new on them they havent been started yet.
So I dont have any updates on what they yield it was also something to just try out and im dissapointed.
But glad I didnt get more.

Have you checked pbmining?

They have a 5 year contract, etc.

The price on pbmining is good, but maybe you should read this thread https://bitcointalk.org/index.php?topic=484355.0 before making your decision. ;)

The most cheaper!

https://lunamine.com/19 

Prefere that site : http://cryptotime.de/

I signed up for pbmining a friend told me to. They are paying so far too.

Do those mining contracts really pay off, though? From what I'm hearing, CEX.io (who are legit, but hash via GHash.io) are hopelessly overpriced and you'll never make a decent return! Why are  people falling for this?

A 5 year contract man? That's an eternity in the Bitcoin world! Bitcoin is only just around for 5 years now, man! That's crazy. I wouldn't pay for 5 years of mining service, nah....

I'm pretty skeptical of all mining contracts, to be honest. I don't think you can make much money renting their stuff. If it really paid off, they'd use their stuff to mine for themselves, won't they? I guess It's only profitable for them!

A 5 year contract is really too long as however much mining capacity you buy now will generate very little in 5 years. With PBmining's contracts you are essentially prepaying for 5 years worth of electricity. Since after some amount of time (less then 5 years) the amount of bitcoin your contract will earn will be less then what they spend on electricity you will be essentially forced to continue mining after doing so is unprofitable, but it is that you pay for the electricity in advance.

Try  http://cryptotime.de  - short and long term contracts. stabile serwers in germany.

seems they are mining with Dell servers lol

Where did U see Dell ? They use ASIC Bitcoin miners, like others ..... Anyway true that offer started not so long time ago...

Which one is best for a newbie to start mining?

I am mining with Genesis-mining.com. It is a multi-algo mining company. You can add on your list. Here is the link of official thread:
https://bitcointalk.org/index.php?topic=602022.new#new

Just try to ask yourself; why are they selling their hashing power to other people..
Its not profitable and highly risky investment; thats why
I wouldn't advise anyone to buy cloud hashing; not now, not ever.

None of them as you won't be able to get your investment back from them.
You can check the profitability yourself with any mining calculator.

Also, the cloudmining sites may disappear at any time.

Cloud miners will always need to upgrade to remain profitable, so I'm waiting to see huge dumping off of older bitcoin mining equipment.

I think involving on BTC mining is not a good choice right now. So I am not thinking about it.
