Since this has been open since 14-Nov with only 1 person wanting to get some spots I will close and lock this soon if nobody else is interested.
I know it's a big risk / reward raffle but I figured some people would throw some BTC just because of that.

I have serious concern whether this cable are able to power-on Raspberry Pi (which could have up to 4 USB device) and an external drive.
Have you used the cable on Raspberry Pi and other USB device without problem (no blinking red LED on Raspberry Pi) ?
Yes, I have 3 of them in use now. I was going to build another one and was looking for the same cable. The Pi in theory can only have 3 USB devices because it is taking up one. But, so long as you have enough amps coming out of the 5V wall adapter it works fine. It's more to keep it neat. -Dave |

So I had a few of these cables:  Basically you plugged a power source into the microUSB female end The male micro USB went into the RPi The USB went into the RPi and the other end went into an external USB drive. The 5V from the power source was what powered the USB drive. Very nice for doing things like this, it kept the cable mess to a minimum. I can't find any more of them, does anybody know where I can snag a few. Thanks, Dave |

It is all triggered simply by THAT address receiving THAT many satoshi's. It has nothing to do with any special magical code or invoice... If I took that payment URL and put it into Electrum (or Bitcoin Core or any other BIP70 compatible wallet) it would still work... all they do is exactly what that website does, connects to the URL and retrieves the appropriate info (ie. what address to send to? how much to send?)
IIRC (and I could be 100% wrong on this) It also sets the fee amount, and does not allow RBF. What I do know: It also allows what is somewhat useful to the merchant is that it allows for the merchant to identify some things about the invoice. I don't like it. But I also don't think it's as bad as some people make it out to be. Kind of a necessary evil for now due to the fact that people still send 1sat fees even when the network is saturated and then bitch that it didn't clear before the end of the business day so their laptop didn't ship. -Dave |

Huh. I didn't even know they had a bitcoin debit card. That's actually interesting and I thank you for mentioning it, even though I wouldn't be interested in having one myself. I thought no one had figured out how to get Visa/MC to cooperate with using bitcoin to load funds onto a card. Guess that's not the case.
Only US based but it's a re-loadable Visa that works quite well. Can also get cash from an ATM. Bitpay isn't a wallet. They may provide some walleting features but their main operation is being a payment processor and they even suck at it sadly. Use something opensource like electrum or something similar instead of that malware. (No need to mention bitpay's main investors are Roger Ver and Jihan Wu which are enemies of bitcoin.)
That's not 100% fair. It is a wallet. There are many better ones out there (and some worse) but to say it's not a wallet is pushing it. BitPay the COMPANY is not a wallet it is as you say a payment processor 1st and foremost and a for profit company. This is why they do a lot of things the way they do. You don't have to like the fact, but it does work for them (for now) and for many other people (for now). And for those of us who are US based it is one of the lower fee ways to convert BTC to cash. -Dave |

And that was probably the last time I ever spent bitcoin on anything.
Hoarder :-) Seriously, the only thing I really use the bitpay wallet for is loading their Visa card. I admit turning BTC into plastic is not always a good thing. But if the merchant does not take BTC, and they are not in one of the categories that has 2x or 3x points on another one of my cards then I sometimes use that card. -Dave |

Is the PP account US based? If not what country is the account based out of?
Conversion fees are an issue. It's almost cheaper for me to spend 6 hours to drive to Canada and do a face to face and drive home then use the crappy PayPal conversion rate. OK not quite that bad but you get the point. Sorry to hijack your post with this but it's becoming more and more of an issue for me (and I assume others).
Also are you sending as F&F or a regular transaction?
Thanks,
Dave

Agree with what everyone else said.
If you red trust the account you can always remove it if you were wrong.
If they don't know they were compromised, then it's another way to reach them. Or let someone know IRL that there is an issue.
I'm a perfect example, there are at least 3 people on this board who have my cell #. If something was off with my account I would like to think that if they saw it at least ONE of them would send me a text or call.

They might not want to generate empty blocks, they might not even be trying to. They just are.
-Dave
This could be the case but it's still a poor excuse not to improve. Their entire service is based on mining blocks and the transaction/rewards to be as profitable as possible for their miners. Transactions are the biggest reason for a miner to choose a PPLNS pool, so not doing everything possible to avoid empty blocks is just letting down your clients. On the flip side of that Miners exist to process these transactions, so if there is even 1 in the mempool it should damn well be in the block. I haven't been on slush for quite some time, but I think the problem has been they are big enough they don't care. There have been a lot of complaints about things like the merged mining rewards, and nothing has come of it. Unfortunately a lot of people just get complacent and don't reevaluate often enough, and if they are still make mad bank on the fees for the blocks mined without facing any real consequence where's there incentive to improve. I didn't say it was an excuse for them not to improve. IF it's anything I listed it's a WORSE reason not to improve. Nothing was particularly difficult to fix. Hardware is simple, to stressed add more. Configuration check around till you find the issue. I started on slush a looong time ago. Left and never looked back. As you said between the merged mining and things like this it looks like they just don't care. -Dave |

yes, while i was connected to the internet.  how is it that been connected to the net whilst "printing to PDF" locally would leave me part fucked? or are you saying in general that when generating paper wallets online regardless of how you save them is risky? If you do it online you are compromised. OK, you might not be but you don't know. Offline air gapped PC only. See here: https://bitcointalk.org/index.php?topic=5198310.0-Dave |

Today a friend of mine asked me to help him install Bitpay on his Windows computer. I thought it would be a breeze, but it was a sh1t show. You are forced to create a Microsoft account and then when you want to download the App the real sh1t starts.  He has Windows 7 installed on his computer and guess what, BitPay requires --> http://prntscr.com/pxwn63 (minimum requirement of Windows 10 version 14316.0 or higher) Most sites require BitPay for the payments, but if people have to go through all this sh1t to setup a wallet, I do understand why they just give up on Bitcoin and just use credit cards and PayPal. I would much rather pull a tooth without anesthetics.. than having to go through that again. BitPay was designed to strip you of all your anonymity. 1) I just downloaded it w/o setting up a Microsoft account. They try to pressure you into it, but you can just keep clicking no. 2) Windows 7 is EOL as of January, you should not be using it for financial transactions. A lot of places are starting to block it now (90+ days out) 3) Since you are saying require bitpay for payments do you mean BIP70 payment protocol? If so there are other desktop wallets that you can use. https://support.bitpay.com/hc/en-us/articles/115005701523-Which-wallets-work-for-a-BitPay-payment-Which-wallets-are-compatible--Dave |

What nobody is talking about loudly (and I have no idea why) is the hit the R's are taking because of the SALT deductions.
Yes, it's easy to say it's only really hurting NY, CA, etc. the big blue states. But it's not.
It's also hitting rich people with a lot of property in other states. They lost 2 friends of mine 1 in SD and one in NV because they both own stupid large amounts of land and even with a very very very (add a bunch more very) low tax rates compared to NY they still were over the new max, a lot over the max.
As I like to say, I am Mr. nobody here. But if I know 2 people they lost because of that (and their spouses and possibly kids) there are probably 1000s more.
As the saying goes it's all about the economy (money)

Thx for all the positive Feedback! We have added more giftcards.
What else is missing?
Going through the list of what I have spent BTC on over the last few months. Any possibility of getting prepaid cellphone refill cards (something like bitrefill)? Also hotels.com. -Dave |

So ... I had a discussion with gmaxwell about ... a while ago ... and he said that the large pools don't purposely make empty blocks any more since it's no longer necessary due to bitcoind being fast enough to not need to do it (though my pool has proven it was never necessary anyway by never having empty blocks, due to never ignoring all transactions if any are available) Anyway, today slush produced an empty block 603351 They also found the block before it, 603350. Now when they found block 603350 and 603351, my bitcoind debug.log shows: CreateNewBlock(): block weight: 3965699 txs: 2506 of 8755 fees: 0.43025836 sigops 17480
UpdateTip: new best=0000000000000000000668604f0acc91d12483ea4837f742dffb910d8c7fd84c height=603350 version=0x20002000 log2_work=91.322655 tx=473721413 date='2019-11-11 20:31:12' progress=1.000000 cache=79.0MiB(579629txo) warning='55 of last 100 blocks have unexpected version'
CreateNewBlock(): block weight: 3965648 txs: 2468 of 6252 fees: 0.20234402 sigops 18841
UpdateTip: new best=000000000000000000136973e9bfdfc7151d9929d33fa95827a4107ec5115eed height=603351 version=0x20400000 log2_work=91.322681 tx=473721414 date='2019-11-11 20:31:41' progress=1.000000 cache=79.0MiB(579654txo) warning='56 of last 100 blocks have unexpected version'
CreateNewBlock(): block weight: 3965469 txs: 2463 of 6290 fees: 0.20634536 sigops 18749
i.e. there were at least 8755 transactions available before they found block 603350, of which they used about 2500, and over 6200 transactions available for block 603351 after processing block 603350. i.e. they purposefully created an empty block 603351 value 12.5 BTC instead of it being at least 12.70234402 BTC and using over 2400 transactions. So I beg to differ with gmaxwell about his claim that slush pool doesn't code to find empty blocks during a block change  Or, they are running hardware that is stressed to the max and cannot keep up. Or they have something very poorly configured. I believe in the concept of never believe people are doing something wrong deliberately. It's usually just incompetence. (Look at the Trezor vulnerabilities) They might not want to generate empty blocks, they might not even be trying to. They just are. -Dave |

what about coinomi? Is it the same case - we have to trust what they say or is it possible to verify if the ownership of the keys?
More or less what TryNinja said. coinomi uses standard BIP32 for generating keys. I use coinomi and like it. Just keep the following in mind: There have been reports of people getting "hacked" and loosing significant amounts. BUT, (AND THIS IS IMPORTANT IMO): 1) There has never been any independent verification of that by trusted people. 2) At least one of the claims has been proven false. 3) There are many people (myself included) that have at times has a lot of money in both the phone and desktop wallet for a period of time with no issues. The other side: 1) Parts are closed source so you really don't know what they are doing. 2) The desktop version for Windows (can't comment on other OS) uses browsercore64.exe which is the open source web browser created by Google. So take that info as you will 3) Since it is BIP32 you can have the exact same wallet on your phone and desktop and laptop. Which is really handy, until it's not. Yes, you can do that with any BIP32 but I have seen it more with coinomi. Which is great till something goes wrong. Was your laptop compromised? Did your kids at home do something? For real money you are best off with a good hardware wallet. Which one is best is a loooong discussion with lots of arguments here. For having Doge and some ETH and some LTC and some DASH and... all together knowing that there is some risk (you have to determine what your acceptable risk level is) then I think coinomi is great. -Dave |
