Cryptocurrencies are getting more and more popular nowadays, because
they completely anonymous, do not require special knowledge for their
use, and available nearly anywhere. Multitudes of banks all over the
world accept cryptocurrencies, and most of Forex brokers use them to
refill their accounts and for traders’ money withdrawal. The very first
and the most popular cryptocurrency is Bitcoin (BTC), and all other
cryptocurrencies are compared to Bitcoin and only after it – to fiat
money. Therefore, when people mention cryptocurrencies, they usually
Initially working with cryptocurrencies required installation of
specialized software, but today one can access his/her personal wallet
using a specialized wallet client program, or online. Special devices
called Hardware Bitcoin Wallets were developed, but there are not so
many of them, and they are useful only for people who operate with
large amounts of cryptocurrencies. The end user prefers online wallets
as the most convenient ones providing quick and easy access to a
person’s funds from any type of device equipped with Browser.
Bitcoin online wallets can be divided into two main categories: true
wallets and "pseudo" wallets.
In spite of the fact, that pseudo wallets provide a user with
address, the funds stored in such wallets do not actually belong to a
user, though they can be used for personal goals. Usually email address
and password are required to get access to a pseudo wallet but
sometimes your mobile number will be used for the same purposes. Some
pseudo wallets require partial or complete identification, that is, to
operate with them you will need to provide your personal data. Such
approach is somehow contradicting with intrinsic philosophy of
cryptocurrency, completely anonymous by default.
The second significant disadvantage of pseudo wallets are minimal
limits usually established by such services. If the amount transferred
to your wallet is less than a minimum indicated by the service, it will
not be credited to your wallet. Cryptonator, as well as wallets
provided by cryptocurrency exchangers, like Exmo,
are examples of pseudo wallets. In some cases, for instance in
btcbank.com.ua, operations with Bitcoin require user’s bank details,
and transactions with Bitcoins lose their anonymity whatsover.

without limitations and free of charge, except for a small commission
for money transfer. The most popular and convenient online wallets are

popular. It has only two language options, English and German, which is
not always convenient for users from other countries.

This Bitcoin online wallet requires mandatory 2-factor authorization
for all users. Developers insist that this approach ensures enhanced
security and better protection of users’ money, but for many users it
just makes things more complicated. In addition, for each operation two
signatures are required. But the service does not have full access to
users’ wallets, so without participation of a wallet owner not
transactions are possible.

Xapo is probably the most secure online wallet, in return, the
service user will not have much anonymity. According to Xapo, the funds
are stored on servers without connection to Internet, and many banks
would envy the level of security provided. However, such type of
security approach doesn’t match well with any idea of assets turnover,
so most probably this statement is more an advertising trick than a
real thing. More important is the fact that Xapo completely
de-anonymizes its users, who need to provide their personal data and to
confirm their ID with actual ID scans. And a user’s mobile phone number
is required to enable any transaction.
