@adaseb as I told you above they changed the unsigned transaction format in version 3.2. So if you are using less than 3.2 on the cold wallet you won't be able to sign unsigned transactions created by a watch only version >=3.2.

Ahh, for some reason I assumed you were talking about version 3.0.2 and I am currently using 3.0.5, didn't realise so many newer versions were released in the mean time.

Version 3.0.2 seems to work perfectly fine with non-segwit transactions when using version 2.7.x on the cold storage system.

Wondering if there are any other vulerabilities besides the fake message between versions 3.0.6 - 3.3.4 which would prompt an upgrade? Looking at the notes, I don't see any severe bugs or vulnerabilites.

https://etherscan.io/chart/difficulty

well, I think some people turn off their mining rig or moved to other cryptos since the hardfork  Huh Huh

even the hashrate didn't drop to much https://etherscan.io/chart/hashrate

The reason why the difficulty dropped but the hashrate stayed constant is due to the ice age being delayed and the block times returning to 14 seconds.

The ice age basically keeps increasing the difficulty even with constant hashrate to keep the block time delayed. This was removed from the new fork and hence the reason for the steep drop. Its normal.
6843  Alternate cryptocurrencies / Mining (Altcoins) / Re: Auto shutdown software? on: March 02, 2019, 07:49:26 AM
You actually don't need any software at all. Basically all GPUs in the BIOS has a failsafe function which sends a signal to auto shutdown the computer when it goes over a certain temperature. I think its usually 90-95C or so.

If you use Claymore however you can make it throttle however at a certain temperature. So if it goes over 80C or so, it can reduce the intensity and run at a lower GPU usage and get the temps under 80C.

i indeed do not discard 3200$ , by the way doesn't this whole topic go against me "discarding" 3200$ anyway  Grin ?

What probability would you give? I'd say 50-50 (at best) if I'm being honest. The lack of V-bottom, the lack of volume on the "recovery".....and based on the similarity to the 2014 market, we have to leave open a strong possibility that we'll plunge below the 200-week MA rather than just hovering above it. I'm leaning towards a painful dip below the December bottom. Fingers crossed that we see a classic recovery off that.

I was around during the 2014-2015 bear market and it was pretty similiar to what we have right now. Basically there was lots of positive news out regarding Cryptos in the news reports. There was lots of positive developements.

However price still kept going lower and lower. Volumes were very low. Retail interest was dying off. Miners were selling all their gear. People were basically expecting double digit Bitcoin and were going to buy at $100, however it never happened.

Eventually out of the blue right after most days had barely any trading activity it just kept going up and up. I remember shorting at $300 because I assumed it would go back down to $200-$250 or even go lower to $100, it never did and I had a large loss.

6845  Economy / Speculation / Re: Bitcoin bulls vs bears... what side are you on? on: March 02, 2019, 07:43:29 AM
I think that all bears are eventually bullish on Bitcoin. If they are trading on a futures exchange like Bitmex. When they short Bitcoin, their profits are paid out in BTC not USD.

So what would be the point in crashing BTC down to $0 and then having a large number of BTC which is useless. Most of the bears shorted BTC because its not organic growth to go from $1000 to $20000 or an even better example is ETH which went from like $7 to $1400 in a little over a year. A pullback was going to happen regardless.
6846  Bitcoin / Electrum / Re: White-hat message when sending transactions with older versions on: February 28, 2019, 05:40:26 PM

I don't use any Segwit tranasctions however, because I assumed it wouldn't work in my cold storage software version.


Thanks for everybody that replied with the info. So far it looks like just a message I can ignore.

You may not use segwit but others may spend segwit outputs in your favour. For example exchanges. Old versions have trouble recognizing these outputs.

If you don't intend to spend money from cold storage anytime soon then you don't have to upgrade the cold wallet (you should still keep the watch-only up to date). But you will have to update the cold wallet when you need to move your coins.

I had a similiar issue to this however it only affected the hot-wallet (watching wallet) because it wouldn't sync. I've upgraded that version and managed to get the transaction signed on the offline computer.

I assumed Segwit was backwards compatible so using old versions should still work?

But for me, PrimeDice plays important role to help me control my pressure after long work days.
After work, I dice several rounds with small mBTC, of course, for fun.

Even when I can't play in my work, I do in the university when I have some dead time between classes. It also bring the attention of the people around me, so it is a conversation opener.

This post reminds me of a story that happened a while back.

I was at a cafe and out of boredom, I went to some dice site which had a faucet. It might of been Primedice or Just-dice or something similiar. Since I was on public wifi, I didn't want to use my actual account with BTC, I just played with the faucet.

Some guy behind me notices and asks what type of game is it. I told him that is dice. And he assumed it was a game that you play for fun and not real money. Then we spent like maybe 45 minutes talking about Crypto and Bitcoin in general.

He was amazed and if he actually bought BTC when he said he would, he would of made a great investment because I think less than a month later is when that crazy rally started.

So its always a great conversation opener because everybody knows what Solitare or Poker or Blackjack is, but most non-crypto people don't know what dice is.

If you are really serious about this and you have a large enough bankroll, I am taking about at least 100 BTC in cold storage somewhere.

Then you need to get custom coding done for a dice site. Don't buy any dice scripts because they all have bugs and many gamblers will find out what version you are using of a script and they will cheat you. Many dice scripts even have undocumented bugs so some smart hacker can just find some exploit themselves and later on go on your website and cheat you.

Your best bet is to hire a scripted coder who can build you one from scratch and you can also pay them a wage and they can maintain the server to make sure no new bugs arise.

However none of this will be cheap but its the only way you can run a dice site properly and gain enough reputation and trust.

This is easily one of the best suggestions on this thread to develop a safe and secure online casino, but there is one thing that you failed to mention.

There is always a possibility that the custom coder could himself/herself hack the casino whenever they want for obvious reasons which is why it would be wise to ask that person to submit his/her KYC which must be verified.

This would effectively prevent the coder from engaging in any wrong-doing in the future.

I understand however this is the reason why he needs to hire someone with a reputation to up-hold.

Most computer programmers who do free-lance work are usually not anonymous, they post their resume in public to get work. They are in the field of programming and not stealing money by hacking.

Usually before you hire someone, you look at their references, and if they decide to scam you, you can always contact their references and say they are dealing with a scammer and they won't get future work.

This is like hiring a lock-smith to change your locks in your house. Sure they can make a copy of the key and rob you in the future. However its very risky for them and they will get a bad reputation for doing so.
6849  Economy / Speculation / Re: Samsung Galaxy S10 Crypto Offering A bullish sign? on: February 28, 2019, 06:45:02 AM
Is this trying to say that we will be able to buy galaxy s10 for bitcoin officialy? Link you posted is down tho.

As far as I know you can't buy an S10 with Bitcoin. There was a Crypto phone made by HTC a few months back and that one you could actually buy with Crypto but definately not the S10.

Your best bet is just to either sell on an exchange and buy it with cash. Or you can use a service which lets you convert your BTC into a gift card on Amazon and use that gift card to buy the phone.

Just because they added a crypto wallet function, doesn't mean they have started to accept any form of Crypto. Just like Elon Musk is very bullish on BTC, but he doesn't have plans to sell his Tesla's for BTCs.
6850  Bitcoin / Electrum / Re: White-hat message when sending transactions with older versions on: February 27, 2019, 04:28:26 PM
Basically been a while since I've last used Electrum. And today for the first time I got the "white-hat" message saying that my version is Vulnerable and to please upgrade at the correct site pointed to: https://electrum.org/

My question is what other vulnerabilites are there exactly besides the fake message when sending the transaction? I use cold storage and rather keep the older versions rather than upgrading both OS versions.

Thank you

You won't be able to do offline signing if you have the old version on your cold storage system. That's because with 3.2 they changed the unsigned transaction format.

You haven't told us what version you are using? There were many bugs discovered in 2018. The json RPC one, a bug related to parsing segwit transactions, a wallet file corruption bug and of course the phishing message. The latter is just a message. It is harmless if you ignore it. If it won't let you spend your coins just switch servers.

The version in my cold storage system is really old. I think its even from 2017. Last year I upgraded to 3.0.5 to fix the JSON RCP exploit on my hot wallet system, I did a test tranasctions on the cold storage system to sign a message, it worked so I just left it as is. I don't recall the version however, will need to power up the system and check in the future.

I don't use any Segwit tranasctions however, because I assumed it wouldn't work in my cold storage software version.

6851  Economy / Gambling discussion / Re: Lessons from poker on: February 27, 2019, 04:12:08 PM
Poker actually does help some gamblers and traders with certain strategies.

For example, one thing I learned with Poker was to never go "Full Tilt". What does tilt mean? It usually means that after you experience a few losses you start and make bad decisions which causes you to lose even more money due to being emotional.

This applies both to gambling and trading in general. Usually when a gambler is losing money, they just "want to play till break-even", and the more money they lose in the process they begin to take larger and larger bets and this usually results in them losing their entire balance in a short while.

Poker, Gambling, Trading is basically all done using money and its very easy to become attached to it too much and it leads to bad decisions this is why its important to always have a clear head and a good risk/reward and know when to stop.
6852  Alternate cryptocurrencies / Mining (Altcoins) / Re: What to mine with 12 RX580 Rack? on: February 27, 2019, 12:17:31 AM
Hey together,
I have two rigs with each 6x RX580 cards. It was just a hobby project some time ago, but I want to get them back on the track.

I just wonder what to mine at the moment.
The most obvious should be just ETH, right? But is it still worth? And what pools would you recommend?

I know the website whattomine.com but don't know a lot about the most profitable coins.

Have you some recommendations? What are you mining at the moment with your GPU miners?

Cheers.


Well I am guessing you shut them down for a reason and it was mostly due to the low ETH price. Right now the ETH price is even lower than when you shut them down most likely so the situation is not really any better.

Basically ever since BTC broke the 2018 support at $6000 it lead to many miners, ASIC or GPU to shut down their rigs entirely because its just not worth it.

Go to WTM and check if the profits is worth it, but unless you got free or very cheap <0.05c kwh power, then its not worth the headache.
Just wait until the markets improve and maybe we will get ProgPOW for ETH soon.

In my opinion this thread should be locked, because it keeps getting bumped every few days and for some people who are impatient they probably end up going into the website, getting their bonus, then finding out about the requried deposit, sending a deposit and getting scammed.

Not everybody reads every post in a thread, so it gets bumped and Google starts spidering it to a higher listing, tricking even more unsuspecting people.

I've suspected this was a confirmed scam the minute this thread was posted. Way too many red flags and most casinos don't just give "free $22", if casinos do give anything its usually the faucet or some promo.
6855  Alternate cryptocurrencies / Mining (Altcoins) / Re: The baddest (as in good) 2 card budget mining setup? on: February 26, 2019, 05:19:27 PM
I think what you should do instead is instead of paying up to $600 for 2 GPUs, you should instead get a dedicated mining rig and buy some cheap $100 used RX series GPUs.

Basically buy like 4-5 of the RX 470 4GB on eBay and buy some cheap Socket 1150 mobo which supports 5-6 PCIe slots and buy some used cheap 1000 Watt PSU and just mine directly on that rig.

This way, if mining never picks up, you can sell most of your parts at cost since they are in high supply right now without many buyers.
6856  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] [BSV] [Bitcoin SV] Original Satoshi Vision on: February 26, 2019, 05:16:41 PM
Bitcoin SV is looking very strong at the moment, especially when most of the alts are down.

Looking at the daily chart, it seems that the 0.02 area is major resistance since it was support back in January before it broke under.

If the 0.02 ratio is broken, then I expect a quick rise to the 0.03 ATH area and over there will most likely be profit taking.
6857  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Ethereum: Welcome to the Beginning on: February 26, 2019, 08:18:01 AM
I hope this we are going to see some bullish market with the news we are hearing because both ETH and Bitcoin will be the most major currencies will be mostly accepted by the major currencies. In the coming years we might expect some good demand for both these blockchain.

The most existing news which can bring bullish market is Fidelity and Bakkt launc. Fidelity will be launched in March and Bakkt still dont have date... But this will bring trillions in crypto  Roll Eyes

https://bitcoinexchangeguide.com/bakkt-launch-could-expose-over-100-million-new-investors-to-adopt-bitcoin-and-other-top-crypto-assets/

https://www.cryptoglobe.com/latest/2019/01/fidelity-with-7-2-trillion-in-aum-reportedly-launching-crypto-custody-in-march/

There is way too much hype around Bakkt. Honestly after hearing about it for over 9 months or so, I still don't understand exactly what it is just another type of Bitcoin futures.

I think a more positive note was the Samsung flagship phone S10 which came with a Crypto wallet which features BTC, ETH and the ERC20 tokens. This is big because many people will notice this wallet on their phone and wonder if "Crypto" might be the next big thing like the internet and it will get their attention. Keep in mind the Samsung S10 usually sells in the millions around the globe.

Betting with over 3 Litecoin, and won with more than 52 litecoin.
It is very high-betting return.
I have a feeling that only winners shown proofs of their wins, losers don't want to show proofs of their losses.
It makes sense.

Just wondering how many rolls he did before he got that 16x. Wink

No matter how many rolls that he might do because on dice game is just matter of luck whether you are going to hit and even you can do it in the first bet, soa as I can say this is nothing more about luck that play a role. And btw 16x is not really a big deal, so might hit it under 1000 rolls or 100 rolls but if you comparing it to 990x or 9900x then this must be really hard to hit
Luck always play the big role hitting that huge multipliers, and if how determined one gambler was, as there's no specific numbers of rolls
when luck will showed up as long as the player/gambler is aiming to hit that target, their determinations will give them a chance to taste
the sweet success.

Also, not to forget how deep the bankroll and how well they manage to extend their stay waiting for the big one.

I think the people that do these really really low odds high rewards bets are usually doing it just in case they get "really lucky" and get a winner sooner than expected.

Basically say you are betting on 990x and you should get at least 1 winner somewhere in the first 990 rolls. I think most people bet and hope to find the winning roll somewhere in the first 100-300 bets or so and they come out ahead, because if they head further towards the 990 rolls, then they pretty much win nothing or lose nothing.

However like the above posters have mentioned, every bet is completely independant of the prior and there is also a chance where you might do 5000 rolls before you finally hit a winner and it will clean most gamblers out, especially if they gamble with a high base bet.

Can we get the official answer: was Ice age a lie?

You do realise that everything in Crypto is open source pretty much. All you need to do is check the source code and you will know if an Ice age will take affect or not.

MUSIC is basically forked off ETH. I don't remember which version they forked from but I am assuming it was the Frontier release. So if you look at ETH block time chart you will see that it wasn't until 2 years later after release that the ice age started to take effect.

MUSIC was released February 2017 so in the next few months we should start getting longer and longer block times and within 6 months they devs will need to do something to prevent a chain halt.

The only critical vulnerability i remember was JSONRPC bug where attacker can brute-force your wallet when you're online and open browser, if your wallet isn't protected, your coins would be stolen immediately.

More info : http://docs.electrum.org/en/latest/cve.html

Yes that is from version 3.0.4 and older, but I am wondering if the  > 3.0.4 versions have any vulnerabilities besides the "fake message"?
