[Golden Finance Express] Paolo Ardoino, CEO of Tether, said in an interview recently that Bitcoin is unique among more than 14,000 cryptocurrencies because it is the only decentralized currency. He pointed out that Bitcoin is the only currency that is purely driven by mathematical rules and basically cannot be changed. He further explained that, in addition to Bitcoin, other cryptocurrencies have different levels of centralization, some are higher and some are relatively low. For these currencies, every month a team of developers releases new software versions, changes monetary policy, inflation or deflation, and constantly adjusts. Ardoino admitted that his views may be controversial, and he also frankly admitted that Tether is a centralized currency, which is different from Bitcoin.
