The cryptocurrencies appeared in 2009 with the creation of the first cryptocurrency, the Bitcoin. The Bitcoin was seen at the time as a temporary trend by many financial analysts. It was the first and only digital currency of its kind that deviated from traditional money and is not in the hands of traditional banks. Delta guides you in these matters. The intention was to use it outside of traditional banks after the economic crisis in 2008 as it had a major impact on the economy around the world and especially on the US dollar. Analysts and banks saw that there was a wave of protest that, however, disappeared rather quickly when the US economy and subsequently the economy in the rest of the world recovered from the crisis. Anyway, the Bitcoin has quickly become a fully-fledged alternative currency. Nowadays it is becoming more and more common for people to buy Bitcoin or to trade with Bitcoin. Besides, besides being a decentralized currency, it also brought something very innovative with it: the blockchain technology. From Delta you will get all the supports and suggestions regarding all these. The result of this is that there is a growing interest in cryptocurrencies that stem from a large number of alt coins based on the principle of blockchain or other equivalent innovative technologies.
