I became convinced this would be an opportunity for altcoins to get a pump rally.
I would say that if nothing completely unforeseen happens, like a real global disaster or some coordinated government attack on Bitcoin, we won't see $20k again ever. Retail investors and institutions would start buying like crazy as soon as Bitcoin drops below the $30k mark because everyone will consider that a huge opportunity. I would also consider it an opportunity. What I am 100% sure about is that we will never ever again see Bitcoin below $10k. For that to happen there must be an event that would kill Bitcoin in its entirety.
