VIT was created for use in the adult entertainment industry and rewards site visitors for watching videos.

Bank of Spain: Crypto Has 'More Risks Than Benefits'

Bank of Spain Gov. Luis Maria Linde said in a recent speech that cryptocurrencies "present more risks than benefits," Coindesk reported. "[Cryptocurrencies] have low acceptance as a means of payment, suffer extreme volatility, present multiple operational vulnerabilities and have been related to fraudulent or illicit activities in many cases," Linde said. He went on to refer to digital asset tokens as "those spurious novelties that do not provide significant improvements and that should be tackled as soon as possible." While he was forthright in his criticism of cryptocurrencies, Linde did laud blockchain technology, which he said offers "interesting possibilities" but is "still not quite mature."
