[Beginner] Questions so stupid I should have made a throwaway
Let's get the most embarrassing question out of the way first. Yesterday I downloaded my first ever crypto wallet Dogecoin qt-1.6. It was 14 weeks behind so I ran it several hours until it was synchronized. Closed the window once syncing was complete, and now I don't know how/where to access it after searching my computer for the file/program. I understand that this question is so dumb that there's no search results on /dogecoin or google, but: Where on my computer is that empty wallet that I synced for hours yesterday? It's obvious I'm not understanding what a Wallet is since I don't know where to find it after running the exe. I want to buy my first dogecoins. I have no other cryptocurrency, this would be my first, and I'm getting the sense that dogecoin is not for new users who can't mine, but for people who are already in the crypto market with bitcoin/litecoin and can convert these into dogecoin. Is this a reasonable assumption, being that I can't just buy dogecoin with credit card/bank account? I made an account on Coinmkt.com and they will only allow purchase through ego pay, ok pay or money order. Searching reddit for how to buy, I found a recommendation of cash -> coinbase -> BTC-e -> Litecoin -> wallet, so is it the same for dogecoin? I have made a Coinbase account, but I'm starting to feel that this "club" is turning out to be a bit more exclusive than I had anticipated and while I don't mind doing some work before I can participate, the barriers for entry are making me second guess whether a total crypto newb is really welcome to jump in without first being serious about Bitcoin to get access. Am I off-base? (I'm a little discouraged but not ready to give up). Edit: You guys are amazing, and I was able to find my dogecoin files (the appdata\roaming folder was hidden), set the dogecoin.exe as a shortcut on my desktop, and am going to give Coinbase a try for buying some bitcoin that I can convert to dogecoin. (I assume there's a tutorial on how to go from Coinbase btc to Doge somewhere?). An hour ago I felt like an outsider, and now I'm looking forward to being part of this community rather than just a confused lurker. Final question for today if anyone sees it: Would Dropbox be an ok place to keep a backup of my wallet once I get some funds in it?
The Absolute Crypto-Coine Beginenrs Guide to MyriadCoin-Mining
Hello, I'm a new member of the Myriadcoin-Community and I made a mining guide for crypto-currency newbies over on my blog. I thought it would fit here as well, hoping that some newbie would discover it upon his quest for mining crypto-coins. (I hope it is ok, that I just copied it over)
The Absolute Crypto-Coin Beginners Guide to MyriadCoin-Mining
I researched the technology behind Bitcoin, especially the blockchain, for the past week because it could have been helpful with my current research on electronic voting that I am doing for my project thesis. During that I was amazed by the simple and yet powerful ideas behind crypto-currency. I was tempted to invest some of my spare money (which is not much as an undergraduate) into crypto-currencies, but was appalled by the weak points of Bitcoin, that become apparent if one researches it. (Malleability, 51% Attacks, Selfish Mining, etc. If there is interest I can maybe try to scramble together an article going in detail about attacks on crypto-currencies) Then I discovered Myriadcoin, which solved most of the problems I had with Bitcoin. Although I myself am quite new to the Myriadcoin-Community I present to you, the absolute crypto-coin beginners guide to Myriadcoin-Mining. The following guide is written for Windows, the process may be similar on Linux/Mac OS but is not 100% the same
Setting up your Wallet
Your Myriadcoin-wallet is very much like your everyday wallet. It holds your currency, and if you lose it your money is gone.
Go to the Myriadcoin homepage
Download The wallet for your OS. (Currently there are Windows and Mac OS Wallets)
Unzip the downloaded
Start the myriadcoin-qt.exe
After the installation is done you should see your wallet stating that your current funds are 0 MYR. At the beginning the wallet has to download all the information from the blockchain, which can take a while. You can see the progress at the bottom of the wallet. Upon pressing the receive-button at the top you will see your automatically generated address. This address can be used to receive Payment. You can generate as many adresses as you want. Under Settings you can Encrypt your wallet, which you probably should do if you plan to use it seriously. Keep in mind, that if you lose your password you have no means to get to your money. Under File you can create a backup and save it somewhere.
Getting to Mine
Mining is the process which verifies currency transactions between accounts. It is simultaneously the process which generates new coins up to a limit. (20 billion is the limit for MYR). To mine a block means to solve a cryptographic puzzle in form of a hash. Myriadcoin uses 5 of those hash-algorithms. If you are a complete newbie to mining and crypto-currencies chances are you do not have specialized Hardware. Because of that it probably is best if you mine using the skein, groestl or qubit algorithms. Do not be scared of the names, I will guide you trough. If you made your mind up which of those you want to use (just pick one, if you do not want to research them) you can go to this post. The following step by step guide is using the skein algorithm with the Modified cgminer and the cryptorus mining pool. The steps can differ slightly if you use a different algorithm or pool, but should be similar.
Go to the above linked post and scroll down to the Standalone Miner Section
Go to the homepage and register if necessary (Lets say my name is Testhans)
Once you registered you should look for the My Workers Option
There create a new worker. (Lets say I make a worker with the name Myry and the password 1234)
Now unzip the Miner you downloaded
Go to the folder of the miner and create a new textfile that you name run.bat
Go to your pool-website and look for the stratum address. (Can be usually found on the startpage, in this my case stratum+tcp://myrsk.cryptorus.com:3333)
The run.bat should look as follows: name_of_miner.exe -o stratum-address -u YouName.Workername -p Workerpassword (For some algorithms you have to set the algorithm as an option too) This is how my config looks with the examples above: cgminer.exe --skein -o stratum+tcp://myrsk.cryptorus.com:3333 -u Testhans.Myry -p 1234 Save the run.bat and you should be able to start the miner through double clicking. A console-window should open displaying the progress. Every time you find a share a message saying something along the lines of "Accepted 214sabc5fe 4/2" should be displayed. You can enter your Myriadcoin-address inside the Account-Options of your pool, so you can receive your share of the coins you mined. Typically you have to arrange the transaction yourself. Usually the miner can take a lot of options to optimize the amount it can mine, but as a newbie you are likely to break more than you get out of it. The standard-configuration of miner-tools is in most cases pretty good allready.
You can find further resources on the bitcointalk-forums and the awesome subreddit. Also there is another mining-guide, which goes into more detail on all of the algorithms and can be quite helpfull if you are just new to Myriadcoin and not to the crypto-currencies as such. If you have any suggestions or questions feel free to leave a comment, and if you found my guide useful and want to share some of your hard-mined coins, you can do that also. My Myriadcoin address is MKF8EPYksAV4Bn7M8HLEMyvEPtq3EWeGVW
