HOW DO THEY WORK? 

 

They are based on the Blockchain technology, but they work exactly like any traditional payment method, so you will need to:

​

- Know the currency you want to use, e.g. Bitcoin, Ethereum or Altcoin.

​

- Have a wallet to store your cryptocurrencies. 

​

- Use Exchange, a platform or a service (cards) to convert cryptocurrencies to/from other currencies, including traditional ones.
