Excellent points, its just one of the beautiful perks of decentralization, it takes risk and profits out of an inner circle and spreads it so evenly that everyone has a share of the risk and the profit based on their individual input.
When a small group of people/investors are spreading themselves all over the market without due considerations like it happened with the dot com bubble, there's bound to be adverse effects. Those adverse effects can be brought to the least minimum by decentralization(there's always an atom of risk no matter how small).
Guess who the "king of decentralization is"?.... Blockchain Technology, father of cryptocurrencies
Thanks for the beautiful piece
