Cryptocurrencies

If you are into cryptocurrencies probably you already know about Bitcoin. Bitcoin is the first cryptocurrency and the most popular, but it’s not the only one, there are more. Some of them are only simple (and bad) Bitcoin copies, but others are innovating by incorporating new technology like smart contracts, like Ethereum. Nobody knows if those cryptocurrencies are going to prevail in the future as a form of payment, or if they are just speculative investments, but nobody can question that their popularity is rising.
