This round of the bull market is strange; when it rises, it gets knocked down, and when it falls, it gets pulled back up. This has happened dozens of times, and indeed many people are publicly trading in waves. However, they are making profits, constantly getting in and out, repeatedly trading waves for profit. Their earnings have multiplied by how many times already, and even if they miss out later, it doesn't matter. So who is actually paying for this money???
