I don't want to think about is that many people criticize the crypto currency, blockchain, mining. They are just fools and do not understand where technology will lead us. We need to look to the future, as far as possible.
I agree that crypto-currencies are now in high demand and their popularity is growing. Thanks to the technology blockchain there are many new projects, because this is a real business.
Many people bypass technology, because they do not understand them and are therefore afraid. But then it becomes the norm.
