First of all it is necessary to pay attention that it is possible to make payment in cryptocurrency only having the e-wallet. Let's look briefly what most popular crypto - purses in the presents time exist to choose that most of which is suitable you for accumulation and the subsequent realization.

1. Mycelium. Feature of this purse in safety of means. This creation is implemented by the backup copy of the account protected by the password from 12 words. The platform for work – Android.

There is a possibility of a currency exchange, without leaving a purse. It is possible to pay off with currency from this purse through the mobile Fold Mobile service. Minus of a purse consists in lack of anonymity. At money transfer to the cash card it is necessary "to light" the passport data. About safety. The Multisig technology allows the translations with use of several keys to which the administration of service has access. Not a really pleasant makeweight to вообщем, quite good, to functionality.





3. Blockchain. The Ososbennost of a purse consists in absolute anonymity and simplicity of the translations. However purchase of bitcoins for cash money is impossible. Safety is ensured by disposable keys. It is possible to create a backup copy of the account.
4. Circle. Instant international transfers in traditional currencies. Technology of contactless payments of NFC of mobile service for Android. An opportunity to make transfers without the commission. Minus – processing of operations takes up to several days. Accounts in bitcoins are insured.

Widespread minus for e-wallets – access for administrators to keys of clients and also a delay when updating balance. Complaints to blocking of purses took place. Bad work of technical support of service.

Thus, at the choice bitcoin purse to owners of bitcoins, it is necessary to focus great attention on technologies of safety and it is desirable on lack of access for administrators to codes and passwords.

However for some reason in all purses occurs just the opposite. Can do it and it is dictated by desire to help quickly the user at emergence of problems, but also with cases of roguish breakings of accounts when all security systems, don't help, quite naturally, to provide compensation from administration of the sums stolen by swindlers. Otherwise, why then the administration needs access? Open question.

Have dealt with purses through which it is possible to pay goods and services with cryptocurrency. It is excessive to say that they have to be filled up with cryptocurrency. Ways of replenishment of purses, i.e. as a matter of fact, process of receiving a crypt, earning is a subject for separate article, and not one. The Mining, bitcoin cranes, ICO– startups – here the smallest part of projects through what it is possible to earn cryptocurrency and to fill up with her your e-wallet. 

Now actually there was a process of payment. On the different websites and services, he of course different, however one moment can be allocated – lack of anonymity. Buying goods, it is necessary to specify the delivery address, that is the idea of cryptocurrency when all anonymously and nothing can be traced, it is a little lost. It is possible that it to avoid it is worth buying not goods and services, and to pay off on services which don't demand input of personal data (requisites of the identity document, the address etc.). But some restriction of application of cryptocurrency will take in that case place that, a clear image, won't please their owners. 

What it is a defect, omission of creators of a crypt or the veiled way of involvement of new people in the process of receiving and realization of cryptocurrency covering the idea of anonymity of cryptocurrency transactions?
