The altcoin bubble is at its maximum and generates a lot of noise and euphoria in the crypto space. Some may argue that this is not a bubble at all, but the influx of smart money, the loss of its positions in favor of the altcoins, that the world has finally recognized the value of crypto currency, and so on. But most probably just build theories on the basis of insufficient data, in the absence of a representation of what really is the cause of the bubble. I think I know the answer. This bubble is inflated by newly-made Japanese investors. Not-very-clever money pouring into the cryptosphere with frightening speed.
