При переводе на карту возникли трудности, банк отвергал платеж. Обратился в поддержку, в течение 15 минут вопрос был решен, перевели на другую мою карту. Оперативная техподдержка, удобный сервис, спасибо за вашу работу!!!

Перевод был произведен супер быстро! А если добавите еще Сбербанк, чтобы комиссия поменьше, лучшего о не пожелаешь! Так держать!

Выводил эксмо рубли на тинькофф - процедура заняла порядка 5 минут, с 25тыс заплатил комиссию 7,5 рублей.

Результатом доволен на все 146%

We know… paying for stuff sucks, but the security hardware wallets offer are unrivaled by software wallets. Below, several well know hardware wallets are compared and contrasted to help find the best Bitcoin hardware wallet for you! Hardware Bitcoin wallets offer the most security out of any other storage method due to them having multiple lines of defense. The Ledger Nano S is the most popular hardware wallet at the moment. It is aesthetically pleasing and extremely secure. The functioning of the Ledger Nano S is simple yet impressive. Bitcoins stored on the device are kept secure with the use of a microchip and a PIN code. Outgoing transactions are only confirmed upon button presses, so even if your computer was infected with malware, it could not move coins without your permission. The Ledger Nano S is made in a way that ensures that all sensitive actions are done inside the protected component integrated on the microchip. No software, app, or hacker can ever gain access to the private keys if the device is setup correctly. In the event your device is stolen, the backup phrase used to set up your wallet can be used to recover the contents of your wallet. The thief will have only a few tries to get by your PIN code before the device wipes itself locally. What I love about the Ledger Nano S is that it is a multi-currency cryptocurrency wallet. Here are some of the other cryptocurrencies the Ledger supports. In the event multiple currencies are stored on the wallet, they each have their own private key. Instructions are included with the device, but we also have a written guide on our Ledger Nano S review. The Ledger Nano S can be used on any computer, regardless of the operating system. The device has two buttons on it that are used to navigate its menus. The left and right buttons correspond to up or down. Trezor is also one of the older names in the cryptocurrency wallets business. Upon initialization, the device asks you for a PIN code. The storage of private keys takes place on the Trezor in a way that the keys are unable to leave the device. Trezor also has two-factor authentication that can be used to add extra security. The most common form of two-factor authentication is Time-based One-Time Password TOTP which allows authentication codes that change every 20 seconds or so to be required for access. Upon initialization of your Trezor , you will be given a recovery seed. This recovery seed helps in recovering information such as private keys and transaction history in case an owner loses their Trezor. The Trezor then displays the specific amount that has been asked for and the address where the amount has to be sent. If you wish to proceed with the transaction, validate it by clicking the correct button on the device. This Bitcoin wallet supports Windows , OS — The decently sized crystal clear screen of the device makes it easy for the user to navigate its menus. KeepKey takes over the management of private key generation, private key storage, and transaction signing. Keepkey defaults to a word passphrase, but 18 and word phrases can be used. For the most part, the longer the passphrase, the more secure your wallet is. This passphrase can be used to recover information and private keys from the device in the event it is broken or stolen. A feature of KeepKey critics often attacks is its lack of complete cryptocurrency support. The whole idea of OpenDime is to be like cash where you physically hand over the bills. In this case, you hand over the OpenDime. For long-term holders of Bitcoin, this might not be your best option as it focuses on in-person transactions. To get started with the device, plug it into your computer. Setup guide instructions are in a readme file that shows upon insertion. The device asks you to insert a random file which is used to create a unique private key. After the key is initialized, load the OpenDime with any amount of currency. Using a small item like a dime, you can easily remove a component to expose its private key. Opendime currently supports Bitcoin and Litecoin although it is possible OpenDime adds new currencies in the future. OpenDime is secure as long as it is untampered with. The private key is completely hidden until the piece is broken off. Hardware components are exposed on the outside of the device but pose no security risk. Digital Bitbox is extremely secure, as it uses Encrypted USB communication, tamper-resistant chips, and the option of two-factor authentication. Offline backups can be created using the Micro SD slot on the device. Digital BitBox is completely open source and available to view here. Open-source code is great to have on any software project as it allows the code to be reviewed for bugs and malicious files. No such files have been found and the project is completely trustworthy. It is possible more cryptocurrencies are added in the future. While this is convenient, you are not keeping your cryptocurrency secure. Private keys ultimately decide who owns the Bitcoin. When Bitcoin is left in a wallet like Coinbase they hold your private key for you. If you want to use your Bitcoin to transact, consider also having a hot wallet. Hot wallets are typically software wallets that store lesser amounts of Bitcoin. These are great for spending Bitcoin on everyday items. You can never be too secure when it comes to cryptocurrency, which is why hardware wallets are the 1 option for storing cryptocurrency. Depending on your needs, certain cryptocurrency wallets are better than others. For most cryptocurrency holders, the Ledger Nano S or Trezor will be your option, due to their outstanding security, clarity on social media and demonstrated field knowledge. Home Best Bitcoin Hardware Wallets Hardware wallets are by far the most secure option for keeping your valuable Bitcoin secure. Hardware wallets cost money. Why are Hardware Wallets so secure? PIN Codes that must be entered in person Backup phrases used to recover private keys from a lost, stolen or broken wallet Offline storage. If done correctly, hardware wallets can be set up without ever exposing them to the outside world. How is the Ledger so secure? You may be thinking… What if someone steals my Ledger!? Does it just store Bitcoin? How do I setup my Ledger Nano S?
