Despite having jumped in and out of the blockchain world numerous times over the years, I love cryptography, currency, and cryptocurrencies.I did, however, always have trouble with cold-storage because I knew I could not secure my coins as well as Coinbase’s Vault… until now.There’s also the fact that Coinbase only supports BTC and ETH.I love Bitcoin because it was the first and is the most popular crypto, but I get excited by all the new crypto contenders.Especially those whose innovations were rejected by the puritanical Satoshist cult, that is Bitcoin.(cou-ZCash-gh)That’s why I got excited by the Ledger Wallet, and it’s support for multiple cryptocurrencies.I’m no longer an active Shibe, but if I buy a hardware wallet, I bloody well want to store my Dogecoin and Litecoin on it!On top of this, the companion apps are open source!I bit the bullet this black friday and bought a Ledger Nano S on sale!This is a story about how you can keep your Nano S in a safe place (say, a bank vault) and yet use the HD capabilities to create a “watch-only” wallet and send bitcoin to it.

It combines bank grade cold-storage security with the ease of an always available deposit address.To do this, you’ll need to:Follow the instructions that come with your Ledger Wallet, and safely write down the 24 word mnemonic seed.Bitcoin, having its roots in cryptography allows a mechanism to derive private keys from a root public key.litecoin rise in priceThe whole thing is outlined in BIP32 but to summarize overly simplistically:This means you can store a Public key on your phone, and use it to derive wallet addresses.win bitcoins every minuteA thief that steals your public key won’t have access to your bitcoin, but will only be able to see your balances.You can safely store the Private key separately (in your Ledger Wallet), and use it only when you need to spend your coins.The format for deriving wallet addresses is standardized in BIP44, and you should read the BIP to understand the rationale behind it.litecoin cpu pool

But for bitcoin, the path is defined as:* Where m represents the master key* Where /x represents the xth derived child key in the sequence* Where i represents the sequence number of the key* Where ' denotes that the child key is hardened.The format for storing the master key via mnemonic words is outlined in BIP39, and those are the 24 words your ledger wallet made you backup.So, to find the HD Public key for your wallets:There are plenty of wallets that allow you to import an HD Public Key, but Mycelium has the most straightforward process.bitcoin gratis mudahI’ve managed to get it done in Copay as well, but for now, we’ll stick to the easiest.If you’re super paranoid, put your Ledger Wallet in a bank vault, and distribute the master key mnemonic using Shamir’s Secret Sharing in different places.But for me, I’ve put the master private key in a bank vault, and knowing that your only get 3 PIN tries before the Ledger Nano S resets itself makes me pretty confident that I can keep it in my home safe.The Ledger Wallet allows pretty flexible measures to save your coins, and I find that it allows you to fulfill the Be Your Own Bank bitcoin popularized.I love the multicurrency feature, and I now have one wallet to rule them all!bitcoin parody video

No products in the cart.Waves is a powerful and straightforward cryptocurrency platform.gta bitcoin minerDesigned for mass adoption, it does not have the complex functionality of Ethereum, but allows fast and easy access to token facilities.After the MobileGo crowdsale, MGO tokens will be available on both the Waves and Ethereum blockchains.Investors who claim their tokens on Ethereum will need an Ethereum wallet – for beginners, MyEtherWallet is recommended.The wallet is a lite client that is designed for the Chrome browser, though it can be used with other browsers if desired.Waves is intended to be extremely user-friendly, so the client does not require a blockchain download.(Anyone can run a full node, but this requires more technical expertise and a balance of at least 10,000 WAVES.)The Waves lite client can be used in two forms: The benefit of the standalone app is that it automatically updates.Whilst the html can be used with a broader range of browsers, it will need updating manually.

The first step is to create an account using a SEED.This is generated by the client and takes the form of 12 random words.The SEED is used to recover an account in the event of hardware failure, or to import one onto a different device.The SEED is like a private key and must be carefully backed up, since if you lose it, you risk losing access to your wallet.It is also possible to Import a new account using a SEED you generate yourself.Since this is just a string of random characters, a bitcoin private key or other key can be used, so long as it is sufficiently complex to be secure.Most new users will want to let the client generate the SEED for them.Your address(es) will be saved by the wallet, and for day-to-day use you will be able to log in with a password, rather than entering your SEED every time.The wallet itself is very intuitive.The ‘home’ page has boxes for your WAVES balance, as well as Bitcoin (via the Waves bitcoin gateway) and fiat currencies, which may or may not be operational.

A list of recent transactions is given below.Token balances (including MobileGo) are shown in the Portfolio tab, which also gives you the ability to transfer them to a new address.Waves is continually being updated and new features added.In due course, the Decentralised Exchange (DEX) will make it easy to trade tokens against each other directly (that is, it will be possible to trade MGO for Incent, without going through WAVES or another currency as an intermediary).New tokens representing fiat currencies will be added as these gateways come online, so it will be possible to trade tokens against EUR, USD and BTC.It will also be possible to lease your WAVES balance to a full node, to help secure the network and to receive an income from staking fees. or join the Waves Slack.Warp Passphrase Optional: your email [as a salt] Please enter a passphraseClear & resetbitcoin security should be entirely down to you, if it is not then there is a chance that who/whatever you are trusting is going to take your bitcoin.

Practically speaking, if you are not in control of your private keys (you aren’t with many online wallets), you don’t have control.My advice is to have most of your bitcoin securely deposited in a backed up, encrypted, trusted, determanistic, opensource wallet.) /#download (httpS not http) On windows the portable version comes with the following warning from the creator ThomasV.If you follow this guide exactly, you are fine to use the portable version.Put the downloaded file on your desktop, double click, hit run Pick your wallet type.Start off with the defaults (Create a standard wallet) You need to write the words in the white box down.Do not save them on a computer in any way.They are your seed, they are the most important thing.With these you can recover everything you need.It is important you write the seed on paper with a pen.Store multiple copies somewhere safe.Electrum now checks that you wrote your seed down correctly.The next box will be click able when you have entered the 13 words correctly.

Now enter a password.This is not needed to recover your wallet if you have the seed but it is important to use a strong password as this is what encrypts the file on your computer.If this is weak and you get malware on your computer you will loose your bitcoin.You can make it very very strong by using 13 words like you did with the seed but make sure you make a note of it somewhere.Leave on default (Auto connect) for now, no real need to ever change this.Electrum will open your wallet.It will show the status in the bottom left corner, initially it may be not connected.In this case the icon in the bottom right corner will be red to show you that you are not synchronised.Just wait for electrum to connect to a server and get synced.This will take less than a minute usually as this is a light client – you will not be downloading the entire blockchain.When connected this icon will be green and your balance will display in mBTC (mili bitcoin, 1/1000 of a bitcoin, 0.001, this can be adjusted to BTC if desired in the settings) Go to the receive tab, here you will have your first receiving address listed.

To copy highlight and Ctrl-C or click the copy icon in line with the address on the right.This can be sent to whoever you want to pay you.When copying and pasting addresses always ensure that the address has not been changed by malicious code by looking at the first and last 2 characters.In this case 1H…pu  (Addresses are case sensitive).The QR code can be scanned to pay to this address too.If you go on your addresses tab you can see all the receiving addresses you have generated.These are generated ‘deterministically’ from your seed.Unlimited addresses can be generated, but only those up to the Gap Limit will normally be generated.You cannot run out of addresses as they are generated as you use them.If you needed more than currently visible you can get more easily.Once you have used an address (spent from it) it will move into your ‘used’ addresses under the change tab.You don’t need to manage which addresses have what amounts, electrum handles that for you.All you need to do is enter the amount and the address you want to send to and electrum will combine funds in different accounts to make the transaction as simply as possible.

(If you do need to use a specific address in the future it is very easy to do that (right click, send from) Now you are ready to backup your wallet.You don’t need to do this as you have your seed.You could email a receive address and then throw your computer in a volcano but you would still be able to recover EVERYTHING from your seed.That’s all your addresses, all the spent transactions ect.If you want to back something up digitally you can copy both the electrum data folder and the electrum.exe (shown below) and save them to a memory stick / in the cloud.This means you can drag this combination of files off your cloud to any computer in the future and access your bitcoins using only your wallet.The danger of this is that if you do this on a compromised computer (malware) you can lose your bitcoin due to keyloggers ect.Personally I recommend putting them in your google drive folder (or equivalent) and running them from there only on your trusted device.This ensures that they are allways backed up online with no effort.

This all requires that you have a strong password to encrypt the files.If you have a weak or even no password then if someone gets into your cloud account they could get into your account.With a strong password (and two factor authentication on google drive for example) and your seed written on paper and stored in 3 different secret locations.You can be sure your bitcoin is safe.For long term storage store your bitcoin in cold storage.This can be done by doing the exact same process as here but removing from inside a clean OS (eg boot from tails/ubuntu running on a memory stick) with no other Hard drive connected and no internet connection.This ensures the data is truly only temporary as no data can be stored if booting from a live environment on a memory stick and you ram is volatile therefore cannot store any data after being powered down.Ideally this would be done from a machine that never again connects to the internet but so long as your memory stick is removed from the pc before reconnecting internet or hhd then you will be fine) If you enjoyed this feel free to donate to 1H69CQT5YEHYFCdzN3UMeGfgwn2pKanPre
