The favorite coins that I like are actually a lot, but only one that I favor is more than the other coins, namely Ethereum, maybe a little I can realize about Ethereum, First of all, Ethereum is a decentralized system, which means it's not controlled by a single regulatory entity. The absolute majority of online services, businesses and companies are built on a centralized system of government. This approach has been used for hundreds of years, and while history proves many times that it is flawed, its implementation is still needed when the parties do not trust each other. The centralized approach means control of a single entity, but also means a single point of failure, which makes applications and online servers utilizing this system very vulnerable to hacker attacks and even power outages. In addition, most social networks and other online servers require users to provide at least some level of personal information, which is then stored on their servers. From there, it can be easily stolen by the company itself, bad workers or hackers.
