I thought like you some time ago, but then, "Hey! They are greedy, but they are a necessary part of the system, not the best part, of course, you need doctors and they are better, but if you don't have volume of money moving between places you wouldn't have liquidity in this decentralized exchangers."

But "bad things"? I believe there are worst things like big bad people with a nuclear power button, crazy people, you know, the kind of people that thinks that they're better than everybody in this room and in the next room.
