s7 R$9500
2  Economy / Services / Offering very limited s7 host $0.12/kwh on: November 02, 2015, 04:33:54 PM
I have access to very cheap but small amount of energy. Only ~4.5kwh. I already have clean space, internet, air conditioner, safety and experienced miner (myself). Place will be nearby 24/7. I already have platinum PSU in box not used yet.
I have been trying to get miners but since my government robs 80% of it through "import tax" everything has been very difficult to me, even after months of pursue. I got scammed more than one time in the process, all while having not much money.

It seems everyday that passes and this energy is unused is a waste of money, so since I cannot get someone to sell me miner I will have to try hosting to other people
I offer $0.12/kwh. No maintenance fee or any other BS. Only $0.12/kwh nothing else, except if you want miner sent back to you (highly not recommended due to very high costs which will kill your roi) then you pay sending costs (you also pay first sending costs to get miners to me, like any other company)
I can negotiate. Location in Brazil (must send with very low invoice price!) I can send funds of mine equivalent to your miners' value to escrow so you can be safe that I will not rob you.
Currently available: ~4.5kwh which is equal to +- 3 s7 with window to overclocking and safety.
Also, if you would like to sell me miner instead of hosting please let me know

I'd rather only work with s7 due to hash/weight and experience with it

Why would f2pool mine a block with only this transaction? A 1mb spam transaction with no fees.
6  Economy / Scam Accusations / Waldohoover (aka coiningsolutions.com / DidHeJust ) stole 16.64122524 btc on: June 29, 2015, 10:47:11 AM
EDIT 7/1/15: I removed irrelevant information from the case. I changed thread's title and removed Waldo's information since he is now willing to deal, even though at as of now absurd terms.
I stopped contacting any other person or community. I had many more people, groups, community, people he works with, justice and law enforcement to contact, spread information and seek help but I will try to solve everything here, in this thread and publicly, for now.

Thank you for your interest. This thread is being constantly updated and more information added.
Please verify the how you can help section.

What happened:
Waldohoover stole 16.64122524 btc from me.

How:
1) I pay waldohoover on the 6th may for 32 antminer s3.
2) He says pallet will be delivered to shipping company in a day and at my house in a few weeks
3) Weeks later, he changes shipment method to best suit him
4) Weeks later he cancels the deal, blames me for it and sells the products to other people
5) He charges me absurd, unlawful and made up fees, stalls me and ends up disappearing with my entire money

During all this time I was kind and offered Waldo other shipment methods, apologized, thanked and offered him a discount. On the other hand, after being paid Waldo never apologized or thanked for anything, treated me in a extremely condescending way I wasn't ever treated worst before and charges me many absurd fees. He gave up on making up stuff and stalling to finally scam me in the end.
Dealing with this person is a nightmare and an ordeal. He is an horrible person, businessman and will rob you, specially if you have no recourse such as being poor or/and live abroad.
After nearly 2 months of scam I open this thread, where most people would do so in a few days instead of two months. Before being paid he was nice and attentive.
In the first week of negotiation I informed him I could not afford to lose money because I was going to have a family in days from then.

PM/Chat Logs:

Waldo denies escrow, says I will have pallet at my door in a few weeks at best


Waldo before being paid

Waldo's excellent customer service treatment after being paid, holding my money for 1 month. Notice how he said he would send me my money... 3 weeks ago!

My last email to him, june 26th morning. Ignored.

Other information about him:
Removed as Waldo now is trying to make a deal, even though absurd.

How you can help:
Send me any information you may have linking to this person
Remove any good feedback or post about him
Leave him bad trust feedback here: https://bitcointalk.org/index.php?action=trust;u=101143
In case you want, here is a copy of what you can write:
Risked BTC: 16.64122524
Reference link: https://bitcointalk.org/index.php?topic=1103279
Type: Negative
Comments: Waldohoover stole 16.64122524 BTC from chalkboard17. Will remove this once the matter is settled. Highly advice you not to trade with him until then. More information available here: https://bitcointalk.org/index.php?topic=1103279

He is now willing to negotiate and his account is already very red as it is. I have no intention to kick who already is on the floor so I think no more is necessary, for now. To those who did it, please keep it there while this is sorted. Thanks a lot to everyone who helped with this!

With your help, you will send a message that bitcoin users do not comply with theft and scamming! Most importantly, you will prevent more people be robbed by Waldo Hoover!
I ask you to please help me, my kid and the future victims of this person. Thank you!

Additional Notes:
I was saving this money for years and when my girlfriend became pregnant I decided to fully use it for my child who was born on the 29th may. My father-in-law allowed me to use his solar panels for mining and I would use the revenue for my kid. Indirectly, Waldo who is rich, adult and lives in a rich country, stole from a poor newborn kid from a 3rd world country.
If you want to spam for your signature campaign saying I should have used escrow or blaming me for being stolen please do this somewhere else. Waldo refused to escrow and he had some reputation. I already know not to trust anyone now and I am carrying too much of a burden as it is.

My guess is he did want to send it at first, however he faced problems and instead of facing his own responsibility he decided to blame me and take my money.
He was unable to send it and cancelled it. I could blame him but I didn't. I was nice enough to offer him a 0.15 btc discount + disregard btc price drop + disregard the mining revenue lost. I was rewarded by him doing to me everything I should have done to him and didn't. This guy cannot be a businessman here and nowhere else.
7  Economy / Scam Accusations / Please lock this thread on: June 29, 2015, 08:41:47 AM
Please lock this thread. I was adding information while I could instead of delivering it all at once. I will make a new thread.
8  Bitcoin / Development & Technical Discussion / Blockchain redownload after crash on: June 08, 2015, 08:22:41 PM
Everytime my computer crashes/reboots while Bitcoin is still running, I have to redownload the entire blockchain again. I believe this demotivates people to run nodes. I suggest this to be fixed so people can run more nodes since it takes a long time to download and process entire blockchain. Perhaps doing backups from time to time, automatically, would be a good idea.
9  Bitcoin / Pools / Is it possible for a pool to steal your hashrate? on: June 04, 2015, 09:13:43 AM
Would it be possible for a pool to use your hashrate somewhere else, fooling miners and blaming luck?
10  Economy / Computer hardware / [WTB] Used S3/S3+/S5 (RAISED PRICES) on: May 17, 2015, 05:59:48 PM
S3: $70
S3+: $75
S5: $325

Mandatory escrow
I pay escrow
I pay shipping
I am in Brazil
You must accept to lower declared invoice price. Won't cost you anything
I buy small quantities such as 1 or 2 as well as large quantities such as 50+. Up to you.
I am open to negotiations
Must be fully working with all chips alive. If there is any small problem I may still buy it under discount

I am thinking on finding a forwarder in the USA, where sellers would ship to them instead to me and then he would ship to me for a small profit rate + costs. PM me if you believe you got the expertise and want to do that.
Thank you.

EDIT 25/5: PRICES RAISED
11  Bitcoin / Mining support / Is this normal? s5 board temperatures difference on: May 17, 2015, 01:29:22 PM
http://prntscr.com/762v8e

My first miner arrived yesterday. Bought from bitmain.
1300 supernova gold psu brand new
Air conditioner + 2 ceiling fans + 1 fan pointing straight to miner. Nothing else being run in the room.
Google temperature says 19c outside. I estimate no more than 14c inside
50mb internet
Already tried everything. Been like this since first start
Fan speed 3700 instead of 3000
All this after running for only 15 minutes. It gets worst as time goes on.

There are three things I want and should inform you all about this company/purchase but I don't want any trouble with bitmain so I will keep these out for now

Aceito escrow (VOCÊ NÃO PRECISA CONFIAR EM MIM, ENVIO O DINHEIRO A UM MEMBRO CONFIÁVEL E CONHECIDO PRIMEIRO, DE NOSSA ESCOLHA, ANTES DE VOCÊ ENVIAR AS MÁQUINAS).
Envio a você primeiro apenas se for excepcionalmente reputável, confiável e conhecido.

Antminer
s1 - R$75
s2 - R$560
s3 - R$260
s3+ - R$280
s4 - R$1875
s5 - R$1100
s4+ - R$3000

Nao importa se forem usados, mas tem que estar em pleno funcionamento, especialmente todos os chips operacionais e ventoinhas. Caso não esteja, me descreva o(s) problema(s) e talvez eu compre mesmo assim, com desconto.
Aceito propostas destes mineradores, outros e materiais. Não perca seu tempo enviando propostas absurdas.
Essa é sua chance de se livrar de mineradores que não pagam - ou não pagarão em breve - nem a energia elétrica industrial de alta tensão, quanto mais residencial ou comercial.
Pago em BTC ou reais (transferencia, deposito, dinheiro vivo etc). Prefiro BTC.

14  Economy / Computer hardware / [WTB] Mining equipment on: May 04, 2015, 07:28:12 AM
I want to buy miners and PSU. If there's anything else you might believe would be a good deal for both of us, offer it too.
As for miners, I can take old miners such as s2, s3 etc but not too old like 2013 stuff. Needless to say I have bargain power over antiquated hardware as nobody wants them, but here's your chance to get rid of these hardware earning some cash instead of throwing it away. 2015 hardware is prefered, used or new.
PSU prefered is supernova 1300 gold 80 plus.

Terms:
I am from Brazil. You may send it from anywhere as long as you acccept to send it as gift or lower invoice declaration as I cannot afford a 120% import tax and fees.
I would like to buy some new or used gear. I haven't started yet but I am not a begginer nor am I desperated. I have spent dozens of hours reading about everything non stop, so don't even bother sending me crap deals or try to rip me off. Don't waste mine and yours' time!
I will only pay first if you are extremely reputable and value not too high.
If you trust me and send first that's fine.
Escrow is doable as long as you pay it and trustworthy and known escrow.

Thank you.
15  Bitcoin / Hardware / ASIC and invoice on: May 04, 2015, 02:54:14 AM
For the past entire weekend I researched on the subject but didn't have much success. I live in Brazil and import tax is 65% + 18% state tax + 6% VAT + wrong usd conversion + courier fees + government will overtax, meaning it will raise the value based on tax regardless of being changed or not. They will just assume everyone does so.
All in all, import tax wouldn't be less than 120%, at minimum. Meaning I buy a miner for me and luckly one miner and half for my corrupt government. If you were unsatisfied with your 15% import tax, guess how do I feel with my tax.

Here is a link to prove what I am saying: http://www.dutycalculator.com/new-import-duty-and-tax-calculation/saved_calculations/view_details/192354003/. You may also research further on the subject if you want. This money will entirely go straight into politicians' pockets and also be used to strict my freedom further.

What I would like to know is if is there anyone or any company that could lower invoice notes when shipping. I am not asking for discount or anything, just instead of declaring a miner for example $350 just say it actually cost $30 so I can fight back against this theft done by government mafia. I'd still pay same price to seller.
I tried tirelessly to contact bitmain but they wouldn't do it although they ask their customers to do it when asking for returned products.
I have access to cheap energy and really would like to mine myself. I expect to purchase at least 3th/s per week permanently.

State lovers please back off with criticism. You only get to pay 1/7 of what I would pay.
Thank you, if necessary please PM me.
