Three main features of crypto are:
Cryptocurrency is an internet-based medium of exchange which uses cryptographical functions to conduct financial transactions. Cryptocurrencies leverage blockchain technologyto gain decentralization, transparency, and immutability
The most important feature of a cryptocurrency is that it is not controlled by any central authority: the decentralized nature of the blockchain makes cryptocurrencies theoretically immune to the old ways of government control and interference.
Cryptocurrencies can be sent directly between two parties via the use of private and public keys. These transfers can be done with minimal processing fees, allowing users to avoid the steep fees charged by traditional financial institutions.
At Fenetix, we have decided to use cryptocurrencies such as Bitcoin, Ethereum, Dash etc. as our primary payment method. Reason behind this decision are many downsides at traditional payment processors like PayPal. Many PayPal's users have problems using it, there are high fees, many accounts are closed with no reason. There is too high risk of fraud and chargebacks.
With Bitcoin and other altcoins, there are low fees, transactions are approved in few minutes and fraud is impossible.
