You mean double-spending?
Ledger nano s doesn't allow to do that sadly


How could I do that?

6860c1ba867067637948e6dc2c66b074c6d467035765fc30b1f185d0c61d5bd4

I sent my transaction with a little low fees (there was no rush, so I expected it to arrive between a few hours and a couple days), but it was on 6th December, right before the huge spike of unconfirmed transactions that came in December and that still remains.

At this point I actually want the transaction to disappear from my Ledger. Problem is I have Ledger Nano S, so it's a wallet that doesn't allow the option to double-spend my coins using a higher fee. I don't know any other way to cancel, I read that after about 2-3 weeks it disappears on its own, but it doesn't seem to be the case.

Is there any way I can make it disappear on my own?

Thank you, really appreciate

Well, I've done a lot of research (a fucking lot!!) and apparently my ASUS P8P67 slots would work just fine. This is what this old machine has:

1 x PCIe 2.0 x16
1 x PCIe 2.0 x16 (x4 mode, black) *1
2 x PCIe 2.0 x1
3 x PCI

So far I think I got it right that it can work with 4 good GPUs (like the GTX 1070), I guess I would have to use some sort of risers because there's no way the GPUs fit into the slots all together.

Still not sure if the Gen 1 slots would handle a 1070, if anyone can help I would be very grateful!

I don't think so, they all use Visa/West Crave as a card provider, and for that very reason all have to comply with Visa KYC policies. If you know one let me know

Yes at least Bitwala are very upfront in all their procedures like KYC and especially with the fees.

They made a comparison between the major card providers, cheapest of the market as far as I know (adv cash second place), totally recommended:

Really? Not KYC policy? I understood this is a policy enforced by VISA and they use a Visa, I dont understand that.

Thank you all for your comments.

What I understood from your advice is that there is no automatic report of information on clients by banks or by Visa, but if required, or if any suspicious activity, they are forced to do that. So I think unless I do something stupid or crazy I'm gonna be fine. At least that's what I understood!

Thank you all again.

Thank you all for the answers!! I appreciate your help!



Ok, that's good to know about the OS. It has already installed Windows 10 on it.

That seems like the best option, I would only need to buy MOBO and GPU and PSU.

1) I guess that MOBO is compatible with DDR3 RAM and 6x 1070 GPU?

2) I have searched through bitcointalk and through google but I havent been able to find the thread, could you link it for me?




Thanks, but I'm not using my pc for anything at all, I want to save some buck by taking advantage of my old RAM, old SSD, etc...





Thank you, but I'm currently living on the wrong side of the Wall ^^

-I guess the MOBO can't handle even 4 of these 8GB GPU beasts, but I'm wondering if I could find some MOBO that can handle 4 to 8 1070's and still be compatible with DDR3 memory and i7-2600k, so I can take advantage of them. Would be a sweet feeling to recycle my beloved old computer. My memory and CPU are also in great condition according to userbenchmark test, so it would be a shame to waste them.

-Also, don't know if I could sneak my GTX 560 Ti in a random slot, or if it's so slow that's even pointless lol but even if I could make 15$ a month would be a great feeling to be able to keep milking it after all these years

Hey there!

I'm preparing my 1st mining rig and I have already decided I'm going to be using the amazing and versatile GTX 1070.

It would be great if I could save money buck by using some parts of my old computer. Here are the specs:

CPU:  Intel Core i7 2600K 3.4Ghz Box Socket 1155

MOBO: Asus P8P67

SSD: SanDisk Extreme 240Gb

RAM: Kingston DDR3 1600 PC3-12800 16GB (2x8)

PSU: Corsair HX650 650W Modular

GPU: MSI GeForce GTX 560 Ti 1GB Twin Frozr II OC

COOLERS: Noctua NH-U9B SE2
Lian Li LanCool PC-K60


I guess MOBO maybe not able to support 6 GPUs, maybe 4? It's my first rig so not terribly necessary to go to 6+, but wouldn't mind changing it any way.

Also, I would say the SSD is in pretty lame condition after 5 years of intensive use, not sure how important its condition is.

Thank you very much in advance guys!

Well I know for a fact that the ECB is asking the banks to "check" all their costumers by 31st December, especially foreign accounts. Apparently they have that power.

Yeah I think that pretty much sums it up, at least it's been my case in the last years. My assumption was there is no automatic sending of data from either Visa nor Skrill to the Government UNLESS required. I think I'm not a target of the State due to my situation (young, never worked, never paid taxes). It could happen, but it's extremely unlikely, and in this case I would just pay the fines, the amounts are not that large so that I could go to prison or something really bad.

I was a little bit more worried because Bitwala is a "bank" from within the EU (Germany), and the amounts are going to be higher, but I will stick to the "stay under the radar" mode, don't do anything stupid like the big transaction I made, and cross fingers. Maybe make some more small transactions in the last of this tax year and then spread what I intend to put out between 2018 and 2019 and then go back to a normal tax situation.


My situation is what it is right now, I could have made things a little different in the past but as for now I cannot change them. It's somewhat difficult to manage like that through life, for example you cannot invest in something different than BTC so that your money doesnt lose value every year, you cannot buy a house, a car, etc., but I intend to go back to normal after a year or so when it will be much easier for me, let's hope this works.

Thanks all for the help guys.

I get it. I made a top up on Bitwala's card a few days ago of a large amount, won't repeat the same mistake again.

Thank you all for your help! Any comment/advice is much appreciated.

Well, then I guess it can get a little tricky. With Skrill, which country do they send the info to? My born country where my passport is issued or the country where my address is on and where I'm living right now?


Anyway, I think if I understood correctly, bottomline is, I can fly under the radar if not doing abnormal activities. How much are we talking about as a "huge" sums? I will be careful and only do small transactions evey now and then. My plans for 2018 were withdrawing about 100k€, maybe a little more, if done patiently could I still fly under the radar? This is far more than what I have been taking from debit card in the recent years, that's why I'm concerned.

And by the way, I would be happy to pay a certain reasonable theft or taxes in exchange for nothing in a country where I barely put a foot on, but at this point it would only create more red flags for my situation, so as for now it's much better for me to try to remain under the radar. I think an inspection against someone like me (never "worked", never made a tax income declaration) would be extremely unlikely.

All the economic/financial system is tied, banks, credit cards, goverment. Credit cards report to goverment what you buy, so goverments can ask for taxes.

Yes but it is one thing that Government can "ask for taxes", and another thing that the Government gets actual reports. I know that if a recieve a transaction for 100k€ in my European bank account it's going to be a red flag and the Bank has to notify the Government. But it's not always so black/white:

For example, in Skrill: I have a EU passport, but the address on my Skrill account is from a non-EU country (where I currently live). I think it's very unlikely that the Government is going to ask Skrill for their databases to see if some of their citizens have an account on an electronic wallet in a foreign country. Besides, the amounts were kind of small. I've been doing that for a few years and I think it's very unlikely I would have problems.

Now with Bitwala is a little bit different as the amounts are and are going to be bigger (not enough to be in jail, don't worry for that haha), and my address is in the country from which my passport is issued and where I'm supposed to pay taxes.

I want to know the very specifics of my case. Should I be worried about Visa sending the information to the Government with Bitwala or with both? As I said I'm not too worried that Bitwala or Skrill themselves are going to send my info to the government, but I don't know about Visa.

I don't know the specifics of my situation here, and some light would help tremendously.


Regarding the "stop scamming your government", I'll just say it's too much assumption from you without knowing me or any of the specifics of my situation.

Hey! Thanks for your response.

I'm not very converned about the bank reporting stuff to the Governments. I've been withdrawing money (from legal activities! hehe) with Skrill debit card for several years and I wasn't even close to concerned. I had my address on Skrill on a different country from where I allegedly live and pay taxes.

Now I'm more worried that VISA, given my address on my Bitwala account is actually the address to a EU country where I should pay taxes for it, will be required this information on me by the Government, or reports to the government. In fact, whether my bank (Bitwala, Skrill, or even Visa) will report or not such activities is my object of discussion! And any help is much appreciated as this worries me a little bit. I think Skrill is also in Gibraltar, so less reason to worry, Bitwala worries me a little bit more (and also bigger amounts of cash withdrawn)

Hey there! New here.

I've been using the Bitwala debit card for a while to withdraw money. I think Bitwala is amazing and actually I'm thinking about investing in their next ICO! the service is perfect and the fees are the lowest in the market.

Anywa, the thing is I'm a little bit worried that they (or Wave Crest Holdings, or VISA) would give my information to ECB or to the Central Bank of the country I live (Europe). I would like to keep withdrawing BTC in the Bitwala card without having to worry about the tax agencies or the government messing around. Do you think they have a way of finding out? I'm a little lost here.

Thank you!
