This topic is closely related to something that's been occupying my mind lately.  I recently bought a ColdCard, and I've spent a few hours tinkering with it before I christen it "The Hardware Wallet."  One of the things about the ColdCard that I like (it's a Mk4, btw,) is that it has a small amount of storage that can be mounted when plugged into a computer's USB port.  The storage can be used to transfer wallet files to the PC after generating them in the cold card.  When the ColdCard is unplugged all the data that was stored in said mount is automatically erased.

What I'm wondering, is if the data is just merely erased, or is completely purged?  I doubt it's overwritten, but since it appears to be RAM is it completely unrecoverable when it loses power?  The device also erases any Bip39 passphrase that's been entered when it's logged off or disconnected from power.  I wonder how secure the device's memory features are.

As for BitcoinGirl.Club's panic attack; The Trezor and it's clones have open source hardware, which is partially why they are vulnerable to this attack vector, but the risk can largely be mitigated by adding a Bip39 passphrase to your hardware wallet.  This is especially important for the Trezor wallets, and any that use their source code.  Even if the hacker is able to steal your hardware, and break into it to extract your seed phrase, there's no way for him to get to your funds if they are locked behind a strong passphrase.  I certainly wouldn't consider this a cure, more like buying you a little bit of extra time to create a new seed and transfer all the funds.

I use passphrases on all my hardware wallets now, even if they are not vulnerable to the attack vector demonstrated in that video.

I've used it to create, sign, send, and receive transactions from a test-net wallet, so I do know that it does indeed work.



No, it doesn't need to create a new seed, it'll create a test-net wallet with whatever seed you have loaded in your ColdCard.  It's worth noting that any Bip39 passphrases you load in your ColdCard will generate new test-net wallets, just like the ColdCard would for main-net.



Other than the checkmark indicating that your ColdCard is in test-net mode, there won't be any changes to the device.  It functions just like it would normally.  To use test-net you'll need to export a wallet for the preferred client you want to use.  I use Electrum, so I exported an Electrum wallet from the ColdCard, and used Electrum Testnet client.  You must use the test-net client, Electrum's main-net client will not open a test-net wallet file, you'll get a warning.

On Windows go to Start Menu> Electrum> Electrum Testnet.  

On Linux, the easiest way (in my opinion) is to start it from the command line:

Agreed, the documentation does in fact seem outdated.  Many of the scrolling screen gifs show options/screens that I don't see on my Mk4.  It would be nice to have a separate documentation section for the different versions just to eliminate any ambiguity.  



I don't know about Ledger, but the Trezor works just like the KeepKey.  There's no specific setting on the hardware itself that sets the device into test-net mode, it all happens on the client side.  I played with this a bit yesterday, and I was able to just plug in my Trezor, start up Electrum Testnet, and the Trezor paired up and I was able to create a new test-net wallet.  I didn't make any transactions, but I suspect it would work just like it does on main-net.

I think 15% is too much.  The more you ask the less likely you are to attract legitimate traders, and more likely you are to attract scammers.  Scammers pretend like they're okay with your rates to use your own greed against you.


Yep! $5 wrenches.





Yes, look into Bisq.  It's a peer to peer exchange that often has face to face offers in various locations around the United States.  There have been a couple of offers in my area, but I've never taken advantage of them.  Bisq's rates are very fair, and there you can see what margins others are asking.  That will give you a better idea of what the market will bear.


BTC is considered an asset by the IRS, and like any other asset they don't care if you buy it for more than it's appraised value.  But, they most certainly do care if you sell it for more than you paid for it.  If you do sell for a profit you'll have to pay taxes on the capitol gains.  If you sell an asset for less than you paid for it, you can claim the difference as a loss (deduction,) to reduce your tax burden.

I can't even figure how tennis is scored, let alone risk a wager on it, lol.  I was thinking England would do much better in the EUFA Nations League, but they haven't been as prolific as I expected.  I wagered some on the NBA finals, but other than Premier League soccer and NFL football I tend to get lost when it comes to gambling.

My other passion is motorcycling, so I do keep abreast of MotoGP racing, but sportsbet.io doesn't have any market for that.

I get the feeling that most of the Brits that hang out here are LFC fans, lol.  I see Arsenal getting some love, but I figure it's mostly from foreigners like me.


Guilty as charged.  I do get excited when I see an American playing in the most prestigious soccer league in the world.  And on my favorite team makes it even better.  Soccer is one of my favorite sports, but it doesn't get nearly as much attraction in the US as American football, baseball, or basketball.  So, to see a fellow American take it to the top tier is pretty darn cool.

I'm no expert at fantasy football (last year was the first time I had played since the early/mid aughts,) but it stands to reason that the more teams, the more difficult it is to pick up a gem.  Whether it's during the draft off the waivers, there are going to be fewer opportunities to find a stand out player.


It looks like the majority is in favor of sticking with the 10 teams we currently have, the following voted for 10:

DireWolfM14
wheelz1200
ChiBitCTy
suchmoon
Hueristic
South Park
bbc.reporter

That's 7 votes for 10, which settles that question.

I'm good with that, I like the idea of having two IR spots.

I guess the whole trade veto thing makes sense if we were playing with a bunch of anonymous strangers on the internet, but I'd like to think we're past that, lol.  This is a friendly league, and I don't see collusion becoming an issue.  I'm good with instant trades.

I've found the documentation to be a bit misleading in some circumstances.  There seems to be some that's still pertaining to the Mk3 or possibly older wallets, and some has been updated to relate to the Mk4.  As for testnet on the Mk4, from the main menu you select Advanced>Danger Zone>TestNet, and their you'll find three options "Bitcoin" (which is mainnet,) "TestNet" and "RegTest."  I played around with Testnet a little bit this past weekend, and worked as I expected.

I tried to trick it, but I can't sign Testnet transactions unless the device is set to Testnet mode.  I've played with hardware wallets and Testnet before, and I was sure I had done so with my Trezors, but I realized it was in one of my old KeepKey seeds that I had all my tesnet coins locked up.  I fired up my old KeepKey (which works much like the Trezor) and confirmed it doesn't have a specific testnet mode.  You just need to pair it with an Electrum testnet wallet and from there everything works as one would expect.

I suppose it is officially "Emirates Stadium."  I've never been there, but isn't still in the neighborhood of Highbury?


Yeah, I can't see him displacing Ramsdale anytime soon.  He'll be in for a rude awakening I'm sure as the PL moves faster than MLS and Concacaf.  It's still good to see an American moving to the PL, and I hope he can contribute.

I'm super excited about Arsenal trading for Matt Turner.  Matt has been amazing on the USNT and for the MLS club, New England Revolution.  I can't wait to see him in action in Highbury.  I've been an Arsenal fan for quite some, with many of my fellow Americans choosing teams with Americans on their roster instead.  So I wonder if my friends who were Everton fans when Tim Howard was playing will be rooting for the Gunners this year.

Stop derailing other people's loan request threads with your own request.  It's rude, not to mention off-topic.  If you don't stop I'll start reporting your posts.

If you want to request a loan, post your own thread or post in the lenders' threads.  alterra27 has his own loan thread where you can make a request.

BTW, the collateral you're offering is only worth $1.  It may get you a loan of about $0.83.

I really like this proposal, so I reset the poll and included this option.  If you've voted, please vote again.

I've never used TrustWallet, but I see they call it non-custodial and since you have a seed phrase it appears that it must be.  At least partially so.  Do you have to use 2fa to send a transaction?  It can be email or sms confirmation codes, or a 2fa app, such as google authenticator.  If so, it's likely that it's a 2 of three 3 multi-sig wallet already.



Say what now!?!?    Where did you upload a private key?  Did you upload your TrustWallet seed phrase?  This sounds like a phishing attack!

PS; report anyone who sends you a PM offering to help, they're actually trying to scam you.

I just want to correct what I had written about the ColdCard and testnet; there is indeed a testnet mode.  Since the ColdCard doesn't sign transactions via USB, it must be in Testnet mode to create a wallet to export.

I'm not a fan of punishing people for doing poorly, that seems like pouring salt on the wound.  There's plenty of incentive to do well, and something like that might sour the experience for someone.  I'd rather keep it as friendly as possible.  But without holding back on the banter, of course.

Two more hard votes for 10 players, that make 3 of us.

I'll sell you mine, even give you a slight discount.

Are you going to hang it from the ceiling of your street tent?

Certainly that argument can be made, and I am inclined to agree with you.  I was merely commenting on shear numbers, Ledger having a bigger market share may have made a bigger impact on attracting end users, and hence mass adoption. 


Couldn't agree more, Trezor is a superior product, and company.  Although the ColdCard is starting to win me over, I can't see myself without a Trezor any time soon.



Haha!  Touché.  Shitcoiners will grow up eventually, and they still need some love in the mean time. 

I'm not sure what you mean by this.  So, if Claire was excluded by 3 DT1 members, and included by only two she would remain on DT2?


I agree, there should be at least two DT1 inclusions at the very least.

It is customizable, as you very well know.


I'm not talking about my network, I'm talking about Default Trust.  You obviously know that the Trust System is customizable, or you wouldn't have customized your own.  This wouldn't change anything for those of us who've customized our trust lists, it would only have effect on those who have not customized there's, i.e. newbies and those who've yet to bother.

---

Here's an example of why I think this is worth discussing; I recently included a member into my trust list who's not very active but has been here for a significant amount of time, and seems to have a good head on his shoulders.  He came to my attention when he questioned me about a tag I left for a suspected scammer, suggesting that I may have jumped the gun.  His concern was admirable, and showed restraint.  I've had the same concerns in other situations.  After looking through the reviews he left for others, and reading some of his posts I decided I wanted to see his reviews in my custom trust system.

Since I'm on DT1, now that I've added him he's on DT2.  My actions have an affect of the trust lists of the majority of forum users.  I don't believe that I alone should have that power.  If some other DT1 member feels the same way about said user, then great, I'm not alone.

Also, if Bob believes he should have that power, that would make Bob specifically the type of person that I say shouldn't have it.

WTF?

@LoyceV, any way to tell how many members have a custom trust list?

According to Bpip you have a net score of +4 inclusions.  Just to eliminate any confusion; for Claire to be on DT2 at least one DT1 member must have her included.  But, if one includes Claire and one excludes he, she will remain on DT2 even though her net inclusions is 0.

I am of the opinion that a net score of +2 should be required for inclusion to DT2.  So, for Claire to be included in DT2, at least two DT1 members would need to include her.  If one DT1 member excludes Claire, she would need a total of three inclusions to be on DT2.  I think this would reduce the Trust System spam that is so common today.  It would also reduce the potential for trust system cliques from developing.

I'm just curious about what you folks think.

Currently, only one DT1 inclusion is required for a member to be included in DT2 status.  In fact, a net score of 0 inclusions is all that is required, for example:  If Alice and Bob are both on DT1, and Alice includes Claire while Bob excludes Claire, Claire will be left with a net score of 0 DT1 inclusions, but that's all that is required for Claire to gain DT2 status.  In this example Claire's reviews will be displayed as "Trusted Feedback" if the user viewing the forum has the default Trust System settings.

Of course anyone can change their own Trust System settings, including the trusted depth of your included members' inclusions.  This is a good way to customize how you see "Trusted Feedback."  However, this is not something most newbies do when they first join the forum.  I don't know what percentage of members use custom trust lists, but I suspect it's on the low side of total active members.

I have mentioned my opinion about this in the past, but I'd rather not sway the voting by expressing it in this post.  I do encourage anyone with an opinion to share it here.

Doh!  That was a brain fart, yes 17 weeks is good with me.  I like the idea of skipping the last week of the season, we don't need to make it any shorter than that.

The other thing I wanted to say is that I'm fine with sticking to the 10 players we currently have.  This is a good crew, and for the sake of keeping a fun league I'm going to vote for keeping it as-is.
