With a mixer doing its job you should get back coins with zero taint. That means there is no correlation between the coins you sent and the coins you got back. Blockchain.info has a taint analysis tool anyone can use to measure taint.

The problem with mixers is this: mixers are popular with gamblers and customers of dark net markets so there is a high probability the coins you get back, while not traceable to the coins you sent, may be traced to the bitcoin wallet addresses of a gambling site or darknet market. When you try to sell those coins for fiat the chainanalysis tools that a company like Coinbase use may raise a red flag.

As long as you save your seed you can recover Electrum each time you start TAILS if you do not want to turn persistence on.

Yes there is some uncertainty if your work will be saved if you exit the GUI before sync is done. If you go to settings in the GUI you will see 'Manage daemon' with buttons to start, stop and show. If you hit the show button you can see progress.

There is no option to type commands in the daemon log but you can stop the daemon with the stop daemon button. That should save your progress but no guarantees. I think a developer would have to chime in here. When I first downloaded the GUI I on purpose started cli from the gui folder so I could use the exit command with the daemon until synced.

Happy Holidays! I would prefer to see price action take a break and hover around $900 for a week or two then a new ATH in the New Year. I hope we could have steady increase and avoid the parabola, but I expect that will be the case, a sharp spike up then a crash once again.

That is why you should only buy hosted mining from reputable companies with a few years of good service, and then only if the provider has an exchange built in to their site so you can sell your TH when you want to. Hashnest and HaoBTC are the largest. They will not run off with your investment. Hashflare promises unreasonable returns so they are either a ponzi or a fractional miner (selling more hash then they actually own.) Hashflare is owned by Sergei Potapenko whose history looks pretty suspicious not someone you would want to invest into.

Mining Sweden started as a legitimate company but appears to have gone scam see this thread here at the forum.

When you spend from a paper wallet your private keys are exposed briefly and bitcoin could be stolen if malware is waiting. Many early adopters used to use Armory and two computers for cold storage. That is still probably the most private way to do it and some still swear by it. Using two computers has largely been replaced by hardware wallets like Ledger Nano S and Trezor. There has never been a reported theft of bitcoin from a Trezor or Ledger. As a bonus using Nano S or Trezor you can use your hardware wallet for secure U2F login to a number of services like Google, Dropbox, Github, etc.

On a late model Win7 machine took just over 24 hours. I think if you move the blockchain you would have to open the wizard and tell the GUI where to find it.

Thanks @dEBRUYNE some newer computers need it also

There are no guarantees. HaoBTC might return your investment in about a year, might not. Hosted mining is for enthusiasts who want to have a little fun mining. Maybe invest $150 and buy one TH. As long as you buy from HaoBTC or Hashnest when the new wears off you can always sell your TH on the internal exchange. Buying at Genesis Mining is never recommended, once you buy there is no way to sell. Just buying and holding bitcoin will probably give you a better return than mining.

Genesis Mining is a for profit company that charges high daily fees of $0.35 per TH and is the last place you would want to invest. If you want to buy cloud mining use a provider like HaoBTC where fees are $0.17 per TH and also has an internal exchange where you can sell your hash when you like. Hashnest also has started selling hosted S9 mining but fees are higher than HaoBTC.

Windows users are reporting problems with the GUI on GitHub. The article at Bitcoin Magazine reporting only 2% adoption of Monero on AlphaBay was lower than expected.

I have seen several posts from reddit users who had difficulties with Coinbase because they used shapeshift or mixers will try to find the links.

@[banned mixer] good luck with your venture. Since you have published the addresses of your cold wallet what steps have you taken to prevent coinanalytics software from identifying and monitoring your send addresses? Once identified companies like Coinbase could close accounts for depositing bitcoin received from a mixing service.

Yes no problem. Are you behind a firewall? You should be able to download any version of Electrum in less than a minute.

You can contact the developer on the Electrum thread here at https://bitcointalk.org/index.php?board=98.0

I just checked the download links and they worked fine.

Ledger uses a smartcard element that is proprietary so Ledger is not fully open source. Trezor has already stated they have no time for Monero ATM as they are working on getting Trezor 2 to market. Next to Ledger Jaxx has been making noise about integrating Monero but found it way more complicated than they expected, if they actually do they have the Ice Cube hardware wallet planned for early 2017.

The GUI will be no more secure than running the wallet from command line. Strong passphrase is essential but Monero could really use adoption by Trezor or Ledger. Ledger is more likely as they have more manpower than Trezor and btchip has already mentioned he is interested. Monero app is not on Ledger's public roadmap yet though. GUI is nice yes but using command line is not really a bother. Paper wallets have a point of failure when you have to import private keys to spend.

Eric, not everyone wants to buy a full miner and host in a colocation center. I keep tabs on the cloud mining providers, own 1 TH at most of them and ViaBTC pays out more per day than HaoBTC 150W Hash-Ex or Hashnest S9. Even though you can get a higher payout with ViaBTC you can't sell the hash like you can with the other providers. That is a downside. I also see no reason to go through a distributor when you can buy direct.

For someone wanting to invest $150 ViaBTC is fine. They only charge $0.05 for power at 100 W per TH/s with a 6% management fee on top of that. I don't consider that greedy like Genesis Mining that charges $0.35 per TH/s in fees. Total fees from ViaBTC average $0.16 per day per TH/s.

If I was to buy a miner and host it I would choose your service sinohash.com but I also would buy the most power efficient miner and that is S9. Many can not justify $1600 for an S9. Avalon 721 costs less but is much less power efficient than S9. After the halving it only makes sense to mine with the most power efficient miner you can buy.

Why don't you take some of the S9s you own and sell hosted S9 mining at 1 TH increments yourself? If you can set the fees so you are rewarded for your time and still have a daily payout higher than ViaBTC you would have a winner. ViaBTC daily payouts averaged .00067450 btc per TH/s over last seven days.

Are you saying you used the same seed in Multibit as your Trezor? If you typed in your Trezor seed in Multibit to restore a wallet your Trezor is now compromised. Tip: don't do anything in a panic you may make matters worse.

Paper wallets can be dangerous for new bitcoin users because you expose your private keys when spending and there is always the change problem. Paper wallets are not safer than hardware wallets quite the reverse. As long as a hardware wallet user keeps the seed safe if the hardware wallet provider happened to go out of business the seed can be recovered in Mycelium. There is no downside to using a Ledger Nano S or Trezor.
