 Blockchain: what it is and how it is used in finance Blockchain is the latest technology, and interest in it has grown along with the popularity of cryptocurrencies. Today, it is not only widely discussed in the world of finance. Blockchain is already being used to store and process personal data and identification, in marketing and computer games. But what is blockchain? Let's spell it out. Literally, blockchain is a continuous chain of blocks. It contains all records of transactions - even tulip bulbs in a botanical garden. Unlike conventional databases, these records cannot be changed or deleted, only new ones can be added. If there are fewer tulips (they died out or were eaten by rodents), the record book keeps the information about how many there were before.

 Bitcoin: new global currency or pyramid scheme? There are increasing reports around the world that a company is starting to work with bitcoins, a cyber-currency that comes out of nowhere: not guaranteed by the state, not issued and not controlled by any central bank. In early December, a Lamborghini car was purchased for the first time in the US with bitcoins, and a university in Cyprus said it would continue to accept tuition fees in bitcoins, despite the fact that the Central Bank of Cyprus is vehemently opposed to this "currency". Now the bitcoin exchange rate, following a ban on cryptocurrency payments in China and warnings from the European Banking Authority, is markedly lower than its November highs, when the value of the virtual currency rose from $100 per bitcoin to $1,241.1 in two months. Experts believe virtual currencies have their merits, but the Bitcoin scheme is very much like a pyramid scheme and is not exactly to the liking of authorities and supervisory auth

Exposing myths about cryptocurrency and bitcoins, how their use is regulated in Ukraine and in the world, taxes have to be paid on bitcoin transactions and what are the risks for owners. Recently, interest in virtual currencies has increased significantly. This is due to the crisis in the domestic banking system, instability of hryvnia, volatility of currency exchange rates and other difficulties faced by businesses.
