Mycelium Wallet 2.2 is out
The new biggest feature is complete support for Tor, though the Orbot app, that connects directly to our nodes running as a hidden service (with a .onion extension). The wallet will now monitor your Orbot connection, launch it if it's not running, and will let you know if Tor access is available or not. Previously if Tor access wasn't available, Android OS would quietly switch it over to open web without us being able to control or stop it. We initially included built-in Orchid library, that would have allowed the wallet to have its own built-in Tor without any third party apps, but it proved to be extremely slow (took a minute or longer to connect and synchronize every time). If anyone has trouble getting Orbot due to it being blocked in your country, let us know and we may host an apk of it ourselves as well. Other changes include:
Multiple fiat selection - you can now select a few currencies at the same time, and cycle through them in your balance, send, and receive displays (just press on the currency code with a tiny triangle in the bottom-right corner)
Creating single key accounts was restored due to popular (aka bos's) demand
Transaction confirmations are now shown as pie charts (yellow to green) as opposed to number of confirmations (doesn't confuse newbies)
In Transactions tab, you can now add outgoing transaction addresses to the address book
Transactions tab now shows fiat values. However, initially these are just values shown at the current price, not historical prices. We will implement historical prices in the future (that would require our server to keep a running record on multiple exchanges and for multiple currencies)
In Transactions tab, added a "Reload Account" button if the list is empty, and "Reload Account" in the menu that you can run any time in case you think transactions are missing
In Accounts tab, split the list of accounts into subcategories, with "HD," "Other," and "Archived."
In Accounts tab, there are now subtotals for each account type, and a total for all active accounts.
The totals can be shown in Fiat or Bitcoin by pressing on the Total number.
Added the option to select miner-fee directly in send-dialog
Connection-logs are now available in the about-dialog
Added bitfinex as price-source
Added option to export xPub/xPriv key of HD-Accounts
NFC icon is shown in the Receive dialog if NFC is available
If wrong PIN is entered, it now shows a PIN reset hint
App now shows a list of changes after each upgrade
[bug] Fix wrong locale for some LT-messages
[bug] Google-Geocoder JSON response changed
[bug] Fix number entry in send-dialog, [GitHub:146]
Now we are on to adding more support for HD accounts such as Cold Storage spending from HD paper wallets and HD watch only addresses, built-in support for Trezor and Ledger, and a slew of other things. Please let us know if you run into any problems, and give us feedback for things you would like us to add to our immense To-Do list. You can download it from Google Play or directly from our site here https://mycelium.com/bitcoinwallet
I realise that some people are not that active in our Discord channel (or have not joined at all), which has quite a lot of community developments and other resources. So I have decided to gather some of the things shared around and post them here - in no particular order. Crypto20 performance snapshots and unofficial community resources:
C20 Space by D0tch and ssaabye. This website allows you track your NAV holdings in a few currencies and provides some top 20 performance data.
Youcandance by Rat. This website was one of the earliest community creations and contains an interesting bubble chart. The bubble chart on the top right represents the following: x-axis: Growth in % of the asset - y-axis: Asset as % of the fund - circle radius: $ amount that the asset has grown or diminished since the last revision.
Graphs and forecasting by Nils. This website provides graphs on C20's performance, and also as compared to the market value. There is also some forecasting.
Firebase by - I forgot, apologies. It's another early creation and provides an interesting distribution graph.
Discord server NAV bot by Moaaz. This informs everyone when a revision has taken place and provides daily statistics.
I've posted this information a lot recently to new miners with NVIDIA cards. This subreddit seemed like the right home for it, and hopefully this is will serve as a helpful starting place to clarify the very basics and get people started. As always, watch your GPU core temperatures closely. Lower hash rates correlate to lower operating temperatures. Play with these features to adjust your hash rate according to the load your GPU can handle. For example, one of my cards has better cooling than the other, so I run them at different hash rates to keep them both in the temperature range that I'm comfortable with. Getting Started (Windows Environment):
Download and install the latest NVIDIA Drivers.
Download and extract the latest version of cudaMiner (SEE BITCOINTALK - CUDAMINER LINK BELOW) .
Create a new text file in the same directory as cudaminer.exe (x32 or x64, depending on your system).
Open text file and enter your configuration into the new batch file (See below for samples. Change settings to match your specific set-up):
Change text file extension to .bat
Execute batch file (not the executable).
To exit, CTRL+C to break, wait, then Y to exit OR press the "Red X"; If the the command window closes immediately, add "pause" to the end of the batch script to view the error.
If running x64 version, try x32 version and compare results.
Command prompt window flashes and closes.
Usually indicates bad syntax or attempting to launch executable. Review batch script settings. Add "pause" to end of batch script to view error.
Stratum Authentication Failed / "HTTP Request failed; No Error"
Indicates connection issue. Review server address & user credentials.
Memory error / Result doesn't validate on CPU / Error 30
You are launching the executable; you cannot do this. Create and launch using batch script instead.

Only for multi-GPU configurations: create multiple .bat files or use comma separated values.
When enabled, it reduces GPU utilization and hash rate to allow for computer use during mining
Enable Texture Cache
(Disabled, 1-D Caching, 2-D Caching) may increase or reduce hash rate, available according to your compute capability - check WIKI CUDA LINK BELOW
Consolidates hash work into a single memory block and can lead to lower memory usage. Is implicitly enabled with Texture Caching.
(CPU Only, CPU Assist, GPU Only) determines how much work will be shared by the CPU. Defaults to GPU Only (2) if not specified.
Autotune, autotune for card generation, or specify particular setting. Defaults to autotune if not specified.
Full URL of the mining server you wish to connect to.
Username (or Username.Workername for pools) & password pair for the mining server for your device.
Verbose output to view block/warp chart and test a configuration.
NOTE ^ : This option is they key to tuning your hash rate and resulting GPU temperature. Choosing "auto" will enable autotuning, allowing cudaMiner to choose the best config. Choosing just "G," card generation code, will autotune for that specific card generation. "GBxW" is the specific setting you choose for the card where "BLOCK" is the row #, "WARP" is the Column number in autotune chart. Your BLOCKxWARP value should not exceed your maximum core configuration (WIKI GPU LIST BELOW), otherwise cudaMiner will crash/return error. For best results, the BLOCKxWARP value should be an exact multiple of your core config.
-For example NVIDIA GT 750M, Kepler card, row 4, column 32 is K4x32 (4x32=128). This is exactly 1/3 of and does not exceed the max core config of 384).
NOTE & : Autotuning reported hashrates are not always accurate, but you can use the results in the benchmark table to choose the ballpark hash rate you desire. If you define a setting or allow it to complete the autotuning, it will then begin the benchmark and show you the average hashrate once you end the sesion (CTRL+C). Before closing the command prompt, you can scroll back up and save a screenshot of the block table. Type "Y" after ending to close the program. Remember to turn OFF the flag -D --benchmark after you are done. This is benchmark mode; cudaMiner will not connect to the pool until you remove this flag
